Aside from his 'dad' trying to rape him. There will be gangrape which is ordered by his dad. The narration made it a bit confusing whether they managed to do that. But it seems they really did based on what Jaemin thought to himself. Which is something along the lines of Daeyoung having marked him is actually good bcs then he won't get impregnated by those people
I read the novel too, yk so yeah, based on what Jaemin thought to himself they managed to gangrape him because. Jaemin lamented bitterly that there was a positive side to the fact that Daeyoung forcefully marked because even tho people raped him he wouldn't get impregnated.And about the pregnancy, Daeyoung lied to him

Before I read this, does it have SA by other people (not ML) or love triangles (or annoying 3rd person)?
