Chisato felt guilty about her daughter, who had to grow up in a single-mother family because of her affair. So when my daughter got married, I decided to do whatever I could to protect her family. However, it was alleged affair of his daughter that his son-in-law consulted. We must avoid divorce. Chisato gave a blow job to her breath with all her heart. I'll pull it out on behalf of my daughter. That was Senri's atonement, and by extension, to protect her daughter's family.
