My mother Ayako, who brought her son Ryuji by herself, since she left her husband. The quiet life of a mother and mother, who had a good relationship with him, was a secret. It was not possible to withstand an unrelated life with a man yet, and it was an affair with a married man in the workplace. And the bad thing happened to be seen by Ryuji. Ryuji knows the unfaithful mother's affection, and trembles with anger, and at the same time the pure love changes to the slightest desire. "If this life is so boring, I'll release it." Ryuji beat the mature body of ayaka.
