*SIGH*

You know some fellows just skim through comics and I'm pretty sure some of these people didn't actually read the whole work. Because there are so many signs that shows Dahye isn't the kind of person that you wrote. If Dahye was a narcissistic b*tch who couldn't stand Yuna not worshipping her, it would be enough for her when Yuna said she is the one as her best friend, stating she is putting her above her girlfriend but Dahye was furious cause she doesn't want to be "friends" and now that she realized her feelings there's no going back. It's obvious that she always felt that way, she was just too afraid to accept that. You don't get all worked up planning events with your friend, getting a car just for that and getting all happy/excited just thinking about it. You don't spend the whole night in front of her door waiting for her, worried sick that you're unable to sleep If you're a f*cking narcissist who only ever cares about being number one #-_-)
Btw at first I shipped Yuna with Jooyoung cause I thought they've had a great chemistry, with Joy I don't see any spark tbh, probably because Joy is a cliche with that too perfect to be true kind of character ¯_(ツ)_/¯ Still the only unlikable person is Yuna imo and I appreciate even her because she is at least realistic. Maybe you'll reconsider all those details before hating on Dahye or maybe you won't, I mean you're free to think whatever after all but the way you're judging too fast and too harsh is concerning for me and that's the only reason I took the time to write this longass comment. These stuff might be about a fictional character but real people get hurt by this sort of mentality. It might not be as easy for other people to accept themselves as it was for you, especially in certain cultures. I know from personal experience cause I live in a Muslim country, it sure as hell wasn't easy for me :/
