My father, who was coaching the local baseball team, was involved in a traffic accident, and I was suddenly forced to look after the team. There's no problem with the coach himself, but his relationship with his parents is quite troublesome... One day, after the tournament ended, we decided to have a social gathering with the parents. As we proceeded to the second and third parties, the last ones left were me and Kuroki's mother... I was drunk and my girlfriend was gone for a while, so I couldn't help but follow her body when Kuroki-san invited me to the hotel! ?
