Since I don't understand Korean I can't be 100 % sure but towards the end seung and young jo got kidnapped by seungs ex sugar mamma/pimp when he manages to kinda escape the young model he had a fling wiith stabs him and there really is a pool of blood that it's impossible to make ii alive.I honestly thought he died for good.
HOWEVER in the extra chapters then we see him in a hospital but again he seems like he dies.But then a man who looks like him appears again but still Young Jo doesn't seem to end up with anyone.
Also I think Min got in prison.
I dont know check the raws yourself and if you understand something different or you know anything different pls let me know. XD

so i've read all the english release untill the last chapter on lezhin and the end is ....somehow, i just dont know how to fill about that.
The big revelation we have is that, the boss revenge was pointless ,Min didn't do anything wrong or it was all a misunderstanding( i forgot about the details). Which made me hate him more, loool, i knew from the getgo that something was off with his revenge...
It's not like i was rooting for min, this guy thought that he was entitled of fmc love because he loved her...men just dont get it, men and women can't be friend; when he first met her, he fell for her, and for whatever reasons thought that being friends will make her realise his feeling, your so wrong boy; you meet a girl you like, just CONFESS; the longer you make, the harder it is and the less likely for her to say YES. you wait because you dont want to break you friendship. So dont let the friendship occured in the first place.
I wasn't rooting for boss , and for min neither. All i wanted was to see fmc growth....the best plot would have been, her breaking up with boss after knowing the truth about the vengance, but she had to stay with him because he "changed" and trully "loved" her for no reason...this guy is a fuckboy, he used to deal with countless girl, even, the "pure" type, why he has to fall for her...what was so special about her that at least one of his countless "ex" didnt have?...Author just followed the cliche plot...so the milestones was the revelation about the "vengance" , what happened after has already been revealed by some previous replies...

Everyone in the comment section is rooting for the boss, wanting him to get his revenge which I can totally understand. But the girl he's using in order to achieve that didn't do anything wrong to deserve her feelings played with! She's so nice and pure, I truly despise the boss.
Can someone spoil me the end? What happens to Young Jo, was she toyed with, is she happy... I'm really curious about this comic but also don't feel like continuing if the only good character suffers because if other's grudges
