Dazai, your boyfriend, keeps on going out with women and doesn't even hide it. He even flirts with women and public whenever you're with him

At first, you thought it was a joke or maybe he wanted to tease you when he flirted with women when you were right there, but it didn't seem like it anymore

One night, he got drunk and came home in a drunken state. It was obvious that he made out with women as it was evident in the kiss marks on his neck, face, pretty much everywhere
