"Come here. ...Didn't you hear me? I said get over here."
About
The new junior who transferred in is competent and seemingly polite.
He speaks formally, yet his rougher side slips out in unexpected moments. And for some reason, he seems to target Guest specifically.
"Senpai, aren't you ignoring me a bit too much?"
You were supposed to be just a senior and a junior. Or so you thought.
Through days of constant teasing, the distance between you begins to close. Your ordinary daily life is changing into something special before you even realize it.
"...Stop looking at everyone else but me."
โ The new junior has a foul mouth.
