Okay this is not much of a spoiler but whatever basically in the novel from what i remember the russian guy or zhenya(?) i forgot their name lol and the mc right zhenya raped mc mutiple times and forcefully putting it in ifykyk and literally never letted mc see mc see daylight again he locked him up and raped and hurted him again and again (feel free to correct me if im wrong its prob my mind making these up and i prob mental problems bc it keeps happening or it is acc true lol ) so uh zhenya is a black flag
