I think it's important to note that the ukee is just too naive or don't mind or stupid, he still thinks being intimate with a mam who is clearly gonna marry his sister is fine?.like dude come on, and this seme takes advantage of this and calls 's**' as so called um 'punishment' so messed up . Iam not complaining iam just used to these kind of things but this manhwa/manhua/manga might seem sweet but it's creepy unlike other manhwa or mangas where things are umm clearly stated I would say spoon fed .
