A normal day in class 3-E at Kunugigaoka Junior High School. Actually... It's a place with a little strange people, and with a little strange events, however, it's fun to be here.

Even more so when these strange school adventures occur with Nagisa, your childhood friend and boyfriend, who is a little reserved with others, but kind. Sometimes you may feel somewhat resentful looks from one of your classmates, Rio Nakamura, however, you don't give it much importance.
