Kaizu Takumi♂

Takuumi comes from a single-parent family, but his father is often away for work, so he lives alone with his stepsister, Sana. He has been childhood friends with Hatano Konami, Ebizuka Shino, and Funada Osamu since they were little. What's more, they're in the same class. He has a rather reserved personality, so there's no talk of romance about him. One night during a school trip, when he started talking about love with the boys in his room, he was the only one who didn't know who he liked. That was the trigger that made him start to become aware of the girls around him.
