Apparently I have germophobia. Maybe because of that girls in my class hate me. One day, they threw me into Yukimura house, a place well-known in the neighbourhood as some hoarder's garbage dump . There I had a fateful encounter with a boy, who's also a hitman.

~ Love story of germophobic girl that bloomed in the garbage house ~

The creature known as man is quick to misunderstand.
The same applies to the the pure middle-schooler Yokoyama-kun: A diligent fellow who does his infirmary duty properly.
"You're so nice. Thank you." The one to say that to him was his classmate Nishino-san, so Yokoyama-kun ended up thinking: ("Isn't she only nice to me?!")
He couldn't help but be hopeful. ("Does she like me?!")

This is the start of the misleading life between the fantasizing Yokoyama-kun and the equivocator Nishino-san.
