The other day, I went to the Oshima residence to greet my girlfriend's mother, Yuka. Even just greeting her made me nervous, but I ran into Yuka's boyfriend and boss, Okumoto, so I didn't have time to greet her. After an unpleasant dinner with the four of us, I was feeling sick from the alcohol I had been drinking and was grumbling to myself when I heard some obscene words. There, I saw Yuka verbally abusing Okumoto. As I was watching through a gap, my eyes suddenly met with Yuka's.
