Yu Miyajima, a mother who was caught in the back of her daughter's boyfriend.

He was heartily blessed with his happy daughter who had been able to have a boyfriend. So he often invited his boyfriend to eat and watch the two young men warmly as his mother. On the other hand, he felt lonely. I am not satisfied with the married couple's life, which decreases in contrast to my daughter who is becoming a woman. Yu forgets that his daughter and boyfriend are in the next room, so he becomes self-consolation. and so immersed in pleasure that he provoked his daughter's boyfriend with a bold finger, without noticing the girl's boyfriend peering at him in excitement.
