It all started with a mobile game. Just anonymous, random chitchat between bros. I didn't know who they were. They didn't know me. We just talked about... the dumbest crap.

My crush on this older girl at school... My sad, lonely virgin status... Even my, uh, gross phimosis situation.

Hey, no big deal, right? It's not like I'd ever meet them in real life.

Except the next day, I find out that those online "bros"?

ALL. GIRLS.

And not just any girls. Girls who live on the same floor of my student apartment. As in, right next door to me, this entire time...!

That's how my blazing-hot summer all began.
