Boku-tachi, Watashi-tachi wa, "Honki ni Benkyou" ga Shitai.

Shouta Majima is a high schooler who loves the night, and is often said to be too serious. He lives in a small town in the countryside, and spends each day doing things that are as average as his height. But at night, he felt he didn't need to be that way. Even so, he decided to sneak into school in the middle of the night one night, and found his classmate Akari Tsukimori, who was usually always sleeping, having a "night class". It was then that his life began to change. According to her, studying can change everything. "Studying opens the door to the world. It makes the impossible possible. It can even make it so you can get out of this town. And of course, I'll easily get 100 on tomorrow's test." Thus begins a new age love story where these two take on the world by night!
