Miki, my classmate who’s always picking fights with me… somehow ended up becoming my little sister!

Even though we live under the same roof now, I figured nothing would ever happen between us—especially since she can’t stand me.

But then, one day she accidentally drank Dad’s alcohol from the fridge, and in her drunken haze… she suddenly came on to me!?

“I… I don’t actually hate you, Kou.”
“Kou… do you like me?”
“Th–That’s…!”
