Kosuke, a gay and an editor of a fashion magazine, enjoys his comfortable mid-30s life. One day he was introduced Ryuta, a young personal trainer who is also a gay, to build up his body. Ryuta was raised in a single-mother family, and gave up going to school to work for supporting his sick mother. Kosuke, who lost his mother early, is fascinated by Ryuta, and eventually they fall in love. It looks everything went well now, but Ryuta had a secret which he couldn't tell Kosuke.
