Invited his best friend's stepmother for love because she was so beautiful

I love my mother, Kana-san. The reason is that Kana-san is not her biological mother, but her father's remarried partner and the woman he has always wanted. After my father passed away, he raised me, a non-blood relative, through college. I want to repay Kana-san, but at the same time, I feel more than my mother. However, his thoughts are interrupted by his best friend Kenji. While supporting my relationship with Kana, Kenji, who was jealous of that relationship, quickly approached Kana.
