Kouki is planting plants in his greenhouse with his eldest sister , Rumiko and niece , Watami

"Are you sure you will marry Erika Yanahara, bro ?" said Rumiko, who was worried about her youngest brother, Kouki.

" Yes, I was forced to do it because of my father, but I did this for Watami's sake, your daughter can avoid the burden of the family's demands as an heir," said Kouki who looked at Watami, then continued planting. He cared about Watami, his niece.
