Makimura Ayaka, mother's close friend, suddenly shows up at the house after a fight with her husband. She insists, "I won't go back until he apologizes," storming into the room with heavy breathing. Kousuke reluctantly listens alongside his mother, but Ayaka erupts in anger and immediately starts drinking. Drunk, she suddenly clings to Kousuke, unconsciously touching his body. Feeling her soft breasts, Kousuke's face turns bright red. Trying to calm his racing heart, he carries the passed-out Ayaka to the bedroom, but her defenseless figure makes his pulse race uncontrollably.
