From today, this person is your mother.

One day, an old man brought a woman with him and told me, "From today, this person is my stepmother." I couldn't accept it and asked my friend Satoshi to harass her. But I never thought I'd do something like that. Satoshi had sex with her mother. I couldn't forgive him and quarreled with Satoshi. He wasn't an opponent he could win, but he couldn't forgive him. And when I saw me, full of bruises and lost my fight, my stepmother gently healed me... Not as a son-in-law, but as a man...
