It seems like my daughter is cheating... Aya, who lives with her stepson, felt responsible. She had caused the divorce due to her own infidelity, leaving her daughter lonely. She had passed on her tendency to cheat to her daughter. If she was the root cause of her stepson's suffering, she at least needed to make amends... She would take on the other person herself. That was the only way Aya could think to make amends.
