Kono Koi, Kanaimasuka?

Four high school boys in love will spell out their unrequited love stories in an omnibus. A love that sprouted while commuting on the train to school, a childhood-friend-turned lover, among others! Heart-pounding, you-don't-wanna-miss stories that paint the fresh excitement of the moment you fall in love!
