My boyfriend is going to college out of state. Nao Himezaki, with whom I have a long-distance relationship.

Even when I was far away, where my boyfriend was. Nao wanted to spend her life... She decides to go to the school her boyfriend went to.

But that school was a boys school until last year ...... And it's a boarding school, so she's not the only one there. Not a single female student was there.

One day, two of her classmates visit Nao's room. I invite him to study with me. Naho was a little confused. He invites them into his room...
