Can someone provide me the spoiler on the ending of this manhwa?

damn, this ending would have been truly horrifying.
But no, the ending of this story is actually the typical happy ever after ending. They get married and had a baby, although it was not specific whether the baby is a boy or girl. But before that happened, ML did do horrible things to the FL. Like, seriously. If it happened to me, I would've preferred to die. But what the OGVillainess did to ML was vile too , so ML's behaviour towards the Lyna now is understandable. But man, you should all brace yourselves for when the ML locks the FL up in that cottage he had made specifically for her.

Is not it that (⊙…⊙ )the professor is into blondie and blondie is into redhead and redhead is into professor and the professor knows it so he is using it to his advantage?

I don't think the prof holds romantic feelings for the ml. In the first chapters when ml answered wooju's call in the presence of cha, the latter didn't have any kind of reaction. I think it's more connected with his mother actually or something like that.
Plus, from the cover the professor's hand touches mc's cheek, so I think at last he will develop romantic feelings towards him. But then, he who knows

(づ ̄ ³ ̄)づ sorry to say this folks but I already got the yaoi vibe and can't bring back my mind to the original story line . Author-nim~ you shouldn't tease us like that gezzz....

Yeah, but it’s more like a bad one. Usually I love it when some of the characters give you yaoi vibes cuz then you have a new ship but I don’t really like this one. I think they look good together and everything, but I think the fact that they did this all behind her back and basically used her only for her powers just leaves a bad taste. The cousin was so manipulative in getting what he wanted and Gaspal didn’t even give a damn about Ivona, so while this does give me a yaoi vibe I would rather they both burn in hell than be together tbh.
(Hope this didn’t sound like I was trying to be rude cuz I do agree, just not with this couple ╥﹏╥)
That was the first time she wore a dress gifted by him and now it's drench in her blood.
How poetic
