She sees her ex-husband as a brother and her brother as her "husband" ?
I know they not blood related but they grew up calling each other brother and sister, under the exact same roof, moreover, she looks exactly like his younger sister (with blue eyes I guess, like the twin).
Even if they don't have a single drop of blood that is similar, it still feels like incest to me and it's pretty inconfortable ....

They may have similar hair and other things but for them, she didn’t look like their sister. A lot of people have those features but don’t look the same.
Childhood friends can fall in love, so they can too. It’s not the same when you know they’re not siblings. Since the beginning they rejected her as a sister. And even when they started to get along, it was more very close like family/friendship than real family. I don’t know if you get what I want to explain

Jooin : " I thought it wouldn't impact you no matter what I did"
What you did ? WHAT DID YOU EVEN DO JOOIN ? YOU WERE JUST DRAGGED AROUND BY HIM EVEN WHEN YOU SAID NO ! You did absolutely N.O.T.H.I.N.G
And let's talk about Yahwi. Bitch ! You trusted your mom and she ... Died ? So you decided to not trust or get attached to anyone so that wouldn't abandon you ? Is that you back story ? The disappointment ... And I was expecting anything (︶︿︶)=凸

This shows that Yahwi's immature as fuck... he's old now to think, you mean that shitty logic was in his mind the whole time? he needs to grow up. That kind of idealism in not working and its not worth pursuing. He should've done something else instead.
If this backstory was shown way back then yawhi will realize that shitty grandpa was wrong and treat Jooin better. But I prefer a different back story, this backstory is cliche, bland, boring and not interesting. Author-nim could've gone to a better route.

The horse was bulkyyyyy holyyyyyy !!!!
And the ML ! I don't think he knows she is a girl, does he ? I like Gender bender stories because the characters attracted to the MC thinks they are gay and goes by a whole life reset about accepting themselves and making others do as well until they discovered that the MC isn't the same sex as them. I am kinda disappointed we don't have that here ... (Unless we will get a later pov of him ?)

I don't know about you guys, but the blond eyelashes guy gives me an uke vibe. An uke WITH our MC Uke (what was his name again ? Riftan ? Let's call him Riftan). I feel like blond eyelashes guy will one day sleep with Riftan, or will come close to that ....
"I won't be swayed by him again" he says while getting in the bed
