Tabun Sore ga Love Nan ja Nakarou ka. That Must Be Love

Synopsis

Ever since his fateful meeting with his first love Hiroto seven years ago, Kenta has been in love with him. Kenta thinks their reunion is fate, but the Hiroto in front of him now can't be bothered with things like love - not when his reputation as "The Gutter" lets him all have the physical encounters he wants anyway. Will Kenta ever hang around long enough to find out why Hiroto changed so much? (Source: Fantasista Inc.)
