My Friend’s Little Sister is Special

Pink.
“Oppa.”
Ah, it became slightly lighter.
“…Oppa?”
“Oh, yes?”
“…You weren’t listening to me, were you?”
Looking at her small, puffed-up cheeks as she grumbled “That’s really too much-“, the corners of my mouth turned up without me realizing it.
While knowing exactly where my gaze was directed.
But from long experience, I knew well that if I handled this wrong, those cheeks would really puff up.
I reached out and lightly tapped her soft cheek with a pop sound, successfully returning it to its original state.
“No, I was looking at your eyes. Really.”
“Anyway, when I’m with you, my eyes are mostly pink…”
“…That’s true.”
But even if it was the same color, observing the subtle changes in her eye color each time and guessing her emotions was one of my small pleasures.
Of course, knowing what her pink eyes meant, and what it meant that her eyes were almost always deep pink when we were alone together, made me a little, no, quite embarrassed.
Whenever I reacted that way, she would blush but smile broadly as if she actually liked it.
“Please make sure my eyes don’t change to another color… okay, Oppa?”
As if they had never lightened.
Cherry blossoms bloomed in her eyes as she looked at me.
