``From today onwards, please take care of me.'' The remarriage partner that my father brought to me was the nurse I admired, Satsuki. Kohei, who was hospitalized for the first time in his life and couldn't tell right from left, was taken by the angel in the white coat who was kind to him. Of course I'm happy to be part of the family. I'm sure she'll make a good mother. However, what Kohei was looking for was not a parent-child relationship, but a lover relationship. Kohei, who has already learned that he cannot reverse his remarriage, decides to cross the line with Satsuki, who has become a mother.
