It is awakened with remembrance

Keisuke's cousin Takuya lost three years' memory in an accidental accident. Takuya asked for a chance to regain his memory, and he wanted to stay in the house of Keisuke for a few days. Unfortunately, Keisuke was away on business trips, but Miho, the wife of Keisuke, who had been interested in Takuya and worried about the afterlife after the accident, welcomed him. It is Takuya that the fragment of the memory revives with Miho. And, once again, he remembered to marry Miho.
