I love my mother, Kana-san. The reason is that Kana-san is not her real mother, but her father's remarried partner and the woman he longs for. After my father passed away, he raised me, who is not related by blood, all the way to university. I wanted to repay Kana-san, but at the same time, I felt more than my mother. However, his thoughts are shattered by his best friend Kenji. While supporting my relationship with Kana, Kenji, who was envious of that relationship, quickly approached Kana.
