Heisuke's parents were investigated for abusing their own child. During the time Heisuke was in the hospital, his paternal grandparents took care of him. He was terribly scared. Most of the time, he would remain in silence. His grandparents weren't offended by his silence as they understood what their precious grandson had gone through.
As for Miss Fujita, in order to appease Kyoya's anger, President Fujita sent his daughter abroad to work at the branch overseas. Although it was under the guise of transferring, it was basically an exile.
While Miss Fujita was forced to leave the country, Kyoya couldn't do much on his hateful mother. The woman quickly hid behind her remarried husband.
Heisuke stayed in the hospital for almost two weeks.
