no she's not? its a polyamorous type relationship. she's not tricking or stringing anyone along she's been honest about what she wants and that's NOT monogamy or vanilla sexual relationships. if they stay with her its because they've accepted those terms. and hyunwoo and dawon iirc (the blonde) are clearly very satisfied with hyesol and get along with her outside of sex too. sunhwee is the wild card in that he seems to like hyesol but also find her to be too much for him to deal with. i cant imagine him being with her longterm unless he changes into a different person in s3. (ne way she's never once staid or pretended to be In Love with any of them to make them stay, thats just no who she is just cause someone has multiple partners doesnt mean they are liars or bad person or slutty or w/e other thing seems to bother yall whenever someone fucks more than one person at a time smh)
None of them have consented to a relationship so not it’s not a polygamous relationship at all. It’s basically the 3 of them trying to win one girl over. You can tell that because the other girl (sorry I really can’t remember their names on the top of my head) tried to make the blonde guy jealous. And then when the blonde guy was getting Attention From her the other guy got mad. It’s the three of them Trying to win her over and she’s not dense, she clearly knows they all like her
yeah they all like her and they've Told her. she's not gaming a system here where she tries to keep them all on the hook by giving each of them just enough attention to make them think they have a chance. she clearly likes all of them. her dynamic with each of them is also very different. they fulfill diff roles in and out of the bedroom. even if u dont like this setup on Principle that's fine but ur projecting ur own moral objections onto the character to make her seem more sinister than she really is. you can make a case that she SHOULD just pick one but nothing in the story indicates that any of them are suffering horribly cause she hasnt "chosen" no one has even asked her to choose. sunhwee was anxious earlier in their relationship cause he thought she'd dump him not cause he thought she'd pick someone else Over him. hyunwoo is anxious not cause she's sleeping with other people (which she's always done anyway) but because she's forming bonds with other people for the first time. even IF she never had sex with sunhwee and dawon and just hung out with them all the time like she is now, hyunwoo would feel anxious because their relationship had been incredibly insular and codependant until they met the blondes. they do sometimes compete with each other (sort of?) for hyesol's attention at times but not for her "love" and she's more or less said she cant have "normal" relationships with people or normal sex or w/e. again the cards on the table, she's not hiding anything up her sleeve. they know what's up if one of them refuses to acknowledge it, that's not on hyesol. but ftr they all seem to be Fine with the arrangement so far, and the main one troubled is Hyunwoo for reasons that arent rly her fault (he has never bothered to find a social network outside of hyesol or try to interact with The Blondes outside of the bedroom, either of these would help him feel less lonely or neglected). neway i dont expect to change ur mind here but i rly had to defend hyesol here cause her characterization makes her alot of things (many of them are not flattering traits) but nothing has ever shown her to be the kind of person ur describing.
*Sigh* I finally found someone who deeply understand the story in this comment section... Actually I've had enough with these guys complaining about hyesol being cruel and lack of consent during their session blahh blah blah, like bruuhh she make herself clear from the very beginning before these guys accepts / enter these kind of relationship with her and they all agree with her terms... Actually Hyesol character is a masterpiece a kind of charac you don't actually like or hate at the same time ...a UNIQUE charac to be exact.
Actually all I can see in these section are shippers who find reasons to turn this story into their own boring accord without understanding the story at all (who am I to talk?... well I respect everyone opinions anyways. )

I really hate how she’s basically playing with all three of them, there’s no way she doesn’t know they all like her :/ like honestly I think the guys should just get together at this point make her mad lol
