My name is Torii Nozomu, a plain, inconspicuous, introvert. A new transfer student, Kirishima Kyoko, came to sit next to me. She's cute, kind, and for some reason, she proactively talks to me, even though I'm a a nerd! A true saint... But I want to get involved with her as little as possible, because she's haunted by a "ghost" that only I can see!...
