SEEEEERIOUSLY
The hatred would be much less if she were another dude, and since she's a girl nobody will even give her a chance. I'm pretty sure she's supposed to be a very nice, friendly, normal character specifically so MC has a genuine choice and not "choice between ML and total asshat" where the result is obvious (and cheap).

Presumably, it's from our lovely global "preference for men in all things", it really messes people up. Sadly. It can be very difficult to step away from that mindset.
I think Yoonjoung is a great gal, and I think a dose of healthy competition is going to be really good for Mr. Angel Wonderful! That's an aspect of life he seems to have missed out on a lot--he's 19 and this is his first experience with jealous anxiety?? It will make him a more well rounded person (๑•ㅂ•)و✧

She a woman and apparently woman dont like woman???? yee, beautiful is it not? I genuinely love this character, its pretty obvious the end ship is gona be BL but daaaaaaamn i think she deserves a lot of love, not all this hate which she absolutely does not deservet (or at least as to the recent chapters, mabybe they'll make her a bad person or idk). I just know the only person we should hate is the main charachter, he got the two finnest people in the university???? jealous ughh isdajfbvsjrn (take the "hate" with a grain of salt).

indeed, tho this woman does not seem to be the "oh i am going to ruin your relationship all together even though I know I have no chances of him loving me but still" like most of the cliches, the most i think she'll do is make them jealous and insecure blah blah blah, but at how this is paced, and how the sister has a crush on her she will prolly give up peacefully and friendly after some chapters,,,
She's so adorable, sweet, genuine and cute, maybe the best female character I ever saw in yaoi, how can someone hate her? I don't understand ╮( ̄▽ ̄)╭
