This is proper realism. We as the audience know that the best friend is lying but Seonho doesn’t. So Seonho’s ultimatum ends up unbelievably selfish if taken out of context. And his tantrum should have been grounds for them to break up there and then because their relationship is so new not at the same level of a dying childhood friend. Seonho is valid to his feelings of not feeling appreciated by his boyfriend. But it’s also ridiculous to expect Myeoung to not care about his best friend being suicidal despite the readers knowing otherwise. The best friend is a total ass for taking advantage of the situation and putting Myeoung in such a position too. Really you can’t be on either side because it was just handled poorly by all involved. Myeoung should have called Seonho immediately after knowing the truth but his bad habit of not sharing his feelings is feeding Seonho’s insecurity and exacerbating the whole issue.

Nice reference with the Devil Wears Prada people always make the mistake that Miranda is the ultimate villain when it’s Andy’s boyfriend and friends lack of encouragement is really the cause of her “negative” spiral. She would have been able to juggle it all if she had just felt validated which funny enough it’s Miranda who provides this for her the most.

Good we are on the same page haha, I almost lost hope! Normally I am ok with the mess that the comment section usually is but in this case I am quite shocked. Well, of course it's just kids but if you were in Muyeong's shoes you wouldn't be ok with the way Seonho would treat you. This is comedy fiction so I'm mild with my judgement but if this was me irl I would have had a good talk with Seonho 4 months ago and if he still wouldn't have been understanding I would've called it quits and he'd be known as an asshole ex forever. With Junseok we have to keep in mind that we really do not know if he is that manipulative. Sure, he is to a degree but he probably also really needs Muyeong by his side. He is hiding it all behind his sly grin but deep-down he is very shattered and depressed and Muyeong knows him well so I think he is pretty aware of the situation. I don't think he lied about the walking thing. Also I don't think Muyeong should've told Seonho about Junseok's feelings because it isn't his place. He waited for Junseok to say it himself and that's the right thing to do. And he doesn't know about Seonho's insecurity, I mean he doesn't even know about all the assuming Seonho does. Imo Seonho is the bad guy here.
As his partner he should be supportive, understanding and selfless. That's what love is all about. Being selfish and egoistic and demanding from your partner to give him your time and love when he has it rough is the opposite of true love. So idk why everyone's on Seonho's side but I feel like it's a good portrayal of today's society and why relationships aren't lasting anymore. Selflessness isn't encouraged anymore. And we see protagonists like Seonho who act selfish towards their partners or end relationships for the most petty shit all of the time. And it's treated like it's a good thing to do and even encouraged. It's realistic, sadly, but it shouldn't be this way, irl at least.
Well this turned into a K-Drama real quick... And poor Muyeong is caught in the middle. Sadly, instead of being understanding and supportive Seonho is acting childish and selfish.
We know both sides, but Seonho doesn't know anything about Junseok and the situation between those two. Of course it's hard on Seonho but the last thing he should do is let that out on poor Muyeong. He isn't trying to be one bit empathetic or understanding. The only thing he is doing is assuming and acting childish while Muyeong is stressed out over his best friend's well-being. Imagine your significant other's best friend asked for your s/o after trying to commit suicide, of course you would let your s/o go and not give him an ultimatum like that just to pressure him into staying with you (especially when he is already so exhausted and emotionally drained). What an asshole move. Well, apart from the suicide thing it is realistic tho and I like that Seonho isn't a storybook puppy dog. Especially for a man in his early 20s being like this is normal way too often. Still, not a cool way to act in an adult relationship at all. This is such a Devil Wears Prada trope tho! Andy's boyfriend and friends act so unsupportive towards her while she is working her ass off and trying to make everyone happy. And you as the viewer should feel like her friends are the good people and Miranda, her boss, is the antagonist. When in reality Miranda is the true hero of the movie. But in this case Junseok is no Miranda.
