I can understand I alwys like 2nd lead cuz they treat uke's better but , in case yeonwu he wants to be treated this way , he always like Taehwan there's is no way and if Alex get involve with yeonwu then his frndship with that girl will ruin I don't think but Alex is soo cute so it's better if he just stay away from them and yeonwu of course won't do anything with Alex but let's see in upcoming chapters

He hate himself? For being gay , I think it's just yeonwu come to US to go away from his family especially his father who always make him protest on homosexuality anyway , it never mentioned he hate himself or I might be missing things , but if it's about Alex I better don't want him to come between them I feel tht Alex is just close to Yeonwu cuz he is frnd of his sister also he might find his face kinda likable or something well won't be sure till english of those raws come out , but I don't hate Taehwan cuz he is also a complicated guy as well , he is not sure about his own sexuality as he has been assault I guess when he was little , can't possible think tht and Yeonwu never wanted anyone else beside Taehwan .

Well, I don't know if I'll explain my opinions correctly (I'm not native English speaker). So first point why I prefer Alex is that he is easy going. I'm probably older than a lot of readers here and I do know that sometimes if someone is very attractive for you or you can feel butterflies in your stomach with him... it doesn't alway mean he/she is the best thing for you. How's your life going and you are getting older and older you discover that if you feel comfortable around someone and have a nice time with him it's more than passion and more than complicated person. When I was young I like complicated guys bcs I thought that I can change them but in reality they never change. Not really. They can seems you different but after a few months or years they'll be almost the same. You are who you are. Taehwan is too much. It'll be hard to make him more friendly and also he never will be so easy going like Alex and that's the point. If you want to be with someone it's always better to believe from beginning that your relationship will be stronger and make you feel peaceful and enjoying every single day. But with Taehwan it'll be like on a swing. You can't predict what is in his mind and he doesn't tell you bcs he has past. Difficult past but still... his past makes him and he can't change his previous experiences. With T it'll be every single day in fear if he has good mood or bad mood. Every single day guess what he has in his mind... well he can be with someone strong or someone who had difficulty past too but not Yeonhwo. Not right not. Let's see... this is only story not reality and there can be happy ending.

Taewan frustrates me. I think he has gotten so used to trying to protect himself he struggles to trust others. Yeonwu is already someone who has violated his trust in the past. He is getting over it, but not completely past it yet. I think what is remaining is causing him to hold back from showing any real feelings. I'm hopeful that seeing Alex and Yeonwu together will give Taewan the courage to let his walls drop. I don't think its homophobia as much as it is a way to protect himself from hurt.
That being said I'm not happy with the level of disregard Taewan has for Yeonwu's feelings. I do believe he is conflicted about it all, he looks a little guilty in the raws when he is thinking about Yeonwu. Yeonwu wishes they could have the same level of companionship they had as friends with the intimacy and it hurts to see him thinking he doesn't deserve that.
It's funny because I'm never a second Male lead shipper. Even if I like the sml I still usually prefer ml. I'm hopeful Taewan will turn this around, and I'm hopeful Alex can also get a happy ending because I don't want to see him hurt either. It's so tough lol.

He hasn't been revealed in the English version yet. He is Esther's brother who has a crush on Yeonwu. He writes his phone number on Yeonwu's hand and Taewan sees it and gets jealous. In the last raw Yeonwu and Alex are hanging out earing ice cream and Taewan sees them and is clearly jealous again but the raws end there. Alex will probably be introduced in the next 2-4 episodes in the English version
Hopefully I'm not the only one who prefer Alex.
Spoilers
I don't think Yeonwu is good match with that homophobic asshole. He isn't comfortable around him. Alex is very good looking. Taehwan is hot but that's all he isn't someone for cute and friendly boy liky Y.
