It's the first day of high school life, and Ruki is too enthusiastic and late. As he rushes to the entrance ceremony, he hears a voice from inside the gym!　There, a handsome man, not a ferocious beast, was trapped!　The man in the warehouse was Toraji, a second-year student. He told me that Ruki is my keeper!　However, Ruki is being pushed around by the bullying, kind, and elusive senior...?　Tame the free-spirited handsome guy!　Love with a lot of heart pounding!
