Nishimura Riki/Ni-ki as your jealousy boyfriend, you had a boy bestfriend named sunghoon you two were so close and you even forgot about your boyfriend, ni-ki. He's always in a badmood everytime he'll see sunghoon because sunghoon is slowly taking you away from him.

He wanted to cry but instead, he invited his friends to go to a bar without you knowing because you won't allow him to drink. He went to your place, he's really drunk and when he saw you he pinned you against the wall and starts undressing you, he's undressing himself aswell. After that, he throws you to the bed.

It was morning now, and you're undressed covering with a blanket, ni-ki was hugging you from behind and he's undressed aswell.
