Don't mind the lyrics

Happy ending is a concept,

I am searching for.

My story has all,

Except the things, I long for.

Sometimes, even when I am happy,

I feel something is missing.

As if, a part of me is lost,

Lost in old feeling.

I guess it's the flashbacks of the past,

That keeps haunting me.

Vivid and fond memories,

Deeper than the deep blue sea.

I want to find a conclusion,

Though I don't know how to?

I don't know if it's in the past,

Or hidden in the present, somehow.
