Forced By OAA To Be His Sucessor.

Hogwarts...

After the Defense Against the Dark Arts (DADA) class ended for the seventh-year students in the afternoon, word about their new professor spread like wildfire among the students.

Even though Professor Leo spent the entire period discussing their understanding of DADA rather than conducting a formal lesson, his approach left a deep impression.

He listened carefully to their opinions, offering insightful perspectives that challenged their views.

His interactive teaching style, coupled with the way he valued each student's input, quickly earned him recognition among the seventh years as a respectable and engaging professor.

It wasn't long before whispers about Leo filled the halls, transcending year levels.

Students from every house, regardless of whether they had attended his class, began talking about him.

But while his teaching methods were one of the main topics of discussion, there was something far more intriguing that captured everyone's attention.

The biggest rumor?

Professor Leo had broken a curse in front of the seventh-year students—on the very first day of class.

This revelation piqued the curiosity of the younger students, who flocked to their older peers for confirmation.

"Is it true? Did he really break a curse in class?"

they asked, eager for details.

When the seniors confirmed the story, the rumor only intensified, twisting and evolving into exaggerated versions of the event.

Soon, various dramatic retellings emerged:

One version claimed that Leo had fought a gigantic, ferocious serpent—several meters tall—with his bare hands, ultimately slaying it by ripping its mouth open. 🐍💥

Another rumor stated that he had broken the curse with a single flick of his hand, causing it to reverse and strike its original caster—instantly dooming them. 😨✨

Yet another claimed that Leo had effortlessly lifted the legendary curse left on the DADA position by Voldemort himself with a mere wave of his hand. 🪄🔥

As these wild tales circulated, the rumors eventually reached the ears of the Hogwarts professors, whose expressions turned grave upon hearing them.

Without hesitation, they all made their way to the Defense Against the Dark Arts professor's office, their faces filled with concern.

The sight of so many professors heading towards Professor Leo's office only fueled the students' speculations.

Were the rumors true? Had Leo really done something unheard of?

Meanwhile, in the Slytherin common room—and even among certain students from other houses—many students wrote urgent letters home, sending them off via owl. ✉️🦉

Whatever had happened in that class, it was enough to shake the entire school.

Even though the curse on the Defense Against the Dark Arts (DADA) position was not a secret,

many had dismissed it as nothing more than a myth or a dramatic ploy by Voldemort to vent his frustration.

However, those from ancient pureblood families knew the truth.

The curse was real.

Hogwarts had never attempted to hide it, and over the years, the school had even brought in several skilled curse breakers to lift it—all of whom failed, unable to even locate the curse's source.

Yet, their new DADA professor, Leo, had broken it effortlessly—without even breaking a sweat. 😲✨

DADA Professor's Office…

Standing before Leo was a visibly worried Professor McGonagall, meticulously checking him for any signs of injuries or lingering effects of a dark curse.

"I'm really fine, Minerva."

Leo reassured her with a gentle smile, shaking his head at her concern.

Sigh~

After thoroughly confirming that Leo was indeed unharmed, McGonagall let out a sigh of relief.

She had been the one who personally delivered his invitation letter and had convinced him to take the position as the new DADA professor.

That responsibility made her feel personally accountable for his safety at Hogwarts.

"Who would have thought… The curse was real and could be broken just like that…"

Slughorn, who stood beside Professor Kettleburn, spoke with genuine curiosity.

Kettleburn, a 32-year-old enthusiastic Magizoologist, was currently the Care of Magical Creatures professor at Hogwarts.

He was obsessed with magical creatures to the point of recklessness—as evident from the fresh bandage covering his left eye.

"Well, a real man won't die… not even at the hands of a dragon!"

Hahaha~

Professor Kettleburn's booming laughter filled the office, his enthusiasm reminding Leo of a certain Blue Beast of Konoha.

The right side of his face bore fresh claw marks—a 'souvenir' from a Griffin.

The injury had happened when Kettleburn, in his excitement, attempted to pat the Griffin's mane to test its sensitivity—only to be met with an aggressive swipe from the creature's razor-sharp claws. 😬🦅

Sigh~

Hearing his friend's usual reckless tone, Professor Slughorn shook his head in resignation.

Despite their age difference, Slughorn and Kettleburn shared a close friendship.

Kettleburn would even bring rare and valuable magical materials from his adventures to gift Slughorn, knowing how difficult they were to obtain in the market.

Knock~ Knock~

Their conversation was interrupted by the sound of knocking at the door.

"Come in..."

Hearing the knock, Leo granted permission for the visitor to enter the DADA office.

"I hope I'm not interrupting anything."

With a gentle smile that practically screamed 'I'm just a kind old man,'

Dumbledore stepped into the office, followed closely by Filch and Madam Pomfrey.

"Professor Morningstar, would you mind filling in this old man on what exactly happened during your class?"

Taking a seat across from Leo, Dumbledore's piercing blue eyes examined him carefully, noting that he seemed unharmed.

Leo nodded and began recounting the events of the class, while the others listened intently.

Of course, he made sure to leave out any mention of the system.

"Correct me if I'm wrong, Professor, but you broke the curse… using your luck?"

After hearing Leo's explanation, Dumbledore's curiosity deepened, prompting him to seek confirmation.

Leo simply shrugged his shoulders and nodded.

"I see... Then, can you tell me what kind of curse it was? Because we've examined the classroom countless times, even brought in expert Curse Breakers to verify whether the so-called 'DADA Curse' was real or not. Yet, every result pointed to nothing."

Dumbledore's face turned serious as he inquired about the nature of the curse.

"It was a Parasitic Curse..."

Leo answered without hesitation.

"A Parasitic Curse, huh... No wonder we couldn't find it. The difficulty of removing such a curse is only a few points lower than a Blood Curse."

Realization dawned on Dumbledore as he leaned back in his chair, deep in thought.

Leo then proceeded to explain how the curse functioned, how it had remained undetectable for so long, and the consequences the original caster would now face—

since Leo had successfully rebounded the curse back to its source.

Sigh~

Hearing it all, Dumbledore could only sigh in defeat.

'Tom… it seems like there is no turning back for you…'

Looking up at the ceiling, lost in thought, Dumbledore grumbled in his heart.

The memories of his first visit to the orphanage, where he met 11-year-old Tom Riddle, resurfaced in his mind.

'I should have guided you onto the right path… but before I could realize it, it was already too late for redemption.'

Closing his eyes, Dumbledore blamed himself for his negligence regarding Tom.

He regretted not noticing the darkness that resided within the boy's heart.

First, it had been his close friend, Gellert Grindelwald, and now, Tom Riddle—both had turned to darkness before his very eyes.

Yet, no matter what he did, he had been unable to stop them before it was too late.

Seeing Dumbledore's resigned expression, Leo couldn't help but feel as if the old man had suddenly aged ten years. A deep sadness clouded his once-bright face.

Sigh~

Letting out another defeated sigh, Dumbledore began recounting his last meeting with Tom Riddle—now known as Lord Voldemort—two years ago.

Back then, Voldemort had come to Hogwarts seeking the Defense Against the Dark Arts position.

However, Dumbledore had firmly rejected his request.

This had enraged Tom, who had roared in fury, declaring that if he could not have the position, then no one would be able to hold it for long!

With those ominous words, he had left Hogwarts, vanishing into the shadows.

Not long after, Voldemort actively began recruiting Dark wizards, gathering them under his banner as he claimed his place as the next Dark Lord and the true heir of Slytherin.

A few months after the incident, a rumor started spreading:

The Defense Against the Dark Arts position had been cursed by Voldemort himself.

At first, it seemed like mere superstition.

But then, for two consecutive years, the professors who held the position either resigned or were replaced under mysterious circumstances.

The pattern was too much to be a coincidence.

Realizing the seriousness of the situation, Dumbledore and the other professors had made every effort to find the source of the curse.

They even hired professional Curse Breakers to investigate.

But each time, the experts had shaken their heads, declaring that no curse existed.

Yet, here and now, the truth stood before them.

Tom had indeed left a curse on the Defense Against the Dark Arts position.

And not just any curse—a Parasitic Curse that fed on its victims' luck.

While the discussion continued, Madam Pomfrey was diligently checking Leo for any anomalies in his body.

After a thorough examination, she took out a small potion bottle, poured two caps of medicine, and gently placed them in Leo's mouth.

Seeing no signs of danger, she nodded with a small, satisfied smile, indicating that Leo was fine—he just needed some rest.

"Rest?"

Hearing that, Leo frowned in confusion.

'Didn't she just say I was fine? Why do I need bed rest?'

"Even though you're fine, it's still good to take some rest,"

Madam Pomfrey stated firmly while closing the potion bottle.

"Now, I will take my leave."

With a nod, she turned around and left the DADA office.

Since it was still working hours, there might be students in need of her attention at the Hospital Wing.

One by one, the other professors also left, until only Minerva remained.

"Don't you have class?"

Noticing that Minerva wasn't leaving, Leo raised an eyebrow and asked curiously.

"No, I don't have any classes today. My schedule concluded this morning."

Shaking her head, Minerva explained that she had already finished her lessons for the day.

"Hmm… Then should we play a game? Like Wizard's Chess?"

After thinking for a moment, Leo suggested with a playful smile.

Spending time alone with a beauty like Minerva? Who would complain? Only a fool—or a gay man.

"____"

Hearing the words Wizard's Chess, Minerva's eyes gleamed with excitement—but then, she paused.

"You need to take rest. Poppy has recommended it."

Shaking her head, she declined Leo's invitation.

"But I'm fine—"

Before Leo could finish his sentence, his vision blurred.

Minerva's face in front of him became hazy.

"Wha… What's happening to me…?"

Hiccup~

Feeling dizzy, Leo staggered like a drunken man, his body swaying uncontrollably.

"Oh… The sleeping potion Poppy gave you has finally taken effect."

Holding Leo firmly, Minerva put his arm over her shoulder to support him.

"Let me help you to the bed."

Each professor's office had a small resting area with a bed, in case they needed to rest after a long workload.

Hiccup~

"I see… I understand now…"

Leo mumbled as he leaned into Minerva's arms.

"It's you… You… You want to drug me… and… and have fun…!"

His slurred speech made Minerva's face turn beet red.

After laying Leo down, she was about to stand up—but before she could, Leo suddenly wrapped his arms around her waist and pulled her on top of him!

"Leo… what are you doing!?"

Minerva's embarrassed voice rang out as she struggled to free herself from his grip.

"Nah… I won't let go… I want to marry you… You're so soft…"

Giggle~

Letting out a sleepy giggle, Leo snuggled closer, declaring loudly.

Meanwhile, in the Outside World…

As Leo was having his fun with a helpless Minerva in his arms, news of the DADA curse being broken had already spread across the Wizarding World.

Many wizarding families had received word from their children at Hogwarts.

Shock and Panic Spread…

Among those most shaken were the pureblood families who had pledged their allegiance to Voldemort.

They had accepted him as their Lord, believing he would lead them to the glory of pureblood supremacy—

And yet…

His curse had been broken.

Unknown Mansion…

CRASH!

The sharp sound of shattering glass echoed through the dimly lit room as Voldemort, seething with rage, threw the cup he had just been drinking from onto the stone floor.

A heavy silence fell over the Death Eaters who stood surrounding their Dark Lord, watching his furious expression with fear and anticipation.

His crimson red eyes gleamed menacingly as he clenched his pale, skeletal fingers into tight fists.

"Unbelievable…"

His voice was low, dangerous, and dripping with venom.

A mere eighteen-year-old boy had outdone him.

And that old fool, Dumbledore, had the audacity to make the boy the Defense Against the Dark Arts professor.

His curse had been broken.

By a child.

His followers dared not speak, afraid that any wrong word would result in instant death.

"Didn't you say… that boy runs a business?"

Voldemort's glowing red eyes snapped towards one of his followers, his voice cold and calculating.

The Death Eaters exchanged nervous glances before nodding hesitantly.

"Good…"

A cruel smirk twisted across his snake-like face as he stood from his throne-like chair, his dark robes billowing around him.

"Then I will personally destroy it."

His voice sent a chill through the room.

"I will crush everything he has built… and show him exactly who he is messing with."

Murmurs of approval rippled through the Death Eaters.

"Our Lord will personally take action!"

Excitement flickered in their dark eyes—they were about to witness their master's wrath firsthand.

But then—

"UGH—!"

A sudden, agonized scream tore from Voldemort's throat.

His body lurched forward, and his hands clawed at his back as an unbearable pain shot through him.

"My Lord!?"

The Death Eaters gasped in shock, watching as Voldemort stumbled, gripping the edge of the table for support.

"What… what is happening to me!?"

His voice was a snarl of pain and confusion, his breath ragged as an excruciating burning sensation spread through his spine—

The very curse he had cast…

Had turned against him.
