Idk, I just love this thing where the authors make us to love and adore these antagonists. But Yule is just plain evil and I think that loving him is the same thing if you loved a rapist. Just wrong on so many levels. I'd be happy if Yule ends up dead even if it takes Kyungsoo to become sad.
And I'm glad that the manhwa is coming to an end. Any further sequel will do no good.
Loving a villain character is not bad at all, dear.
To the contrary, I find villains way more interesting than heroes. In every aspect of the word. Why would I latch onto characters like Kyung-soo (and I love him too, don't get me wrong), when a character like Yule gives me everything I need?
He was presented to us like a total asshole... and little by little, the autor has introduced more aspects of him that make us understand.
I usually don't reply to comments on my posts because people tend to get... sensitive. Mostly because I am, indeed, a villain lover, I will always get attached to the bad, psycho, perverted, cannibal, etc guys... but... "Loving him is the same thing if you loved a rapist"... no, darling. it's not the same.
I love stories. I am an avid reader and a writer myself.
Writer, dare I say, of same characters like Yule. I find them interesting and easy to write, therefore, I always get excited over characters in manga/TV shows/books or whatever that resemble the ones I write. It's inspirational in many levels.
So... no. It's not the same. I am not loving a real life rapist, I'm loving a character that has every element to be a fucking amazing character in a not-at-all plain story. ;)

YULE BABY, NO.
I swear to fuck, if he ends up killing himself, I'm going bald, I will declare war to my neighbor, the health of many people will decrease and all the flowers will stop doing the photosynthesis.
I CAN'T WITH THIS, OKAY.
FuCK!
The fact that he had all those trembling hands, or that he could not sleep, or that he just. . . stop being /himself/ for the absence of Kyung-soo just tells many MANY things about Yule. He misses, he craves, he /needs/.
I love my damaged baby, Is2fg I do.
And he doesn't deserve to die like that, being pressured by someone else. Yes, he commited crimes and all, but goddamNIT WITH THIS. MY PSYCHO BABY I JUST. I HAVE EMOTIONS.
