Y'all What?

I agree with you. I actually think her character is very realistic and as you said If I were to have a friend like that I wouldn't need any enemies. Nayun is the kind of person you can know and be acquaintance with but never a close friend. It feels like she will just pass of you if she finds anything bothersome and she'll still think they ain't not issue cuz it ain't her problem once she let go

Yes, like romi communicated, told you how you made her feel, and your response was "huh? Ok bai"

And then to greet her like nothing is wrong? Very tone deaf, read the room. I don't think it makes you a bad person to feel frustrated that you've had to take care of someone like that. Or to be jealous, Romi was happy for Nayun, but she was also jealous which is totally OK.

I look forward to their reconciliation though!

Romi chooses to suffer alone instead of communicating how she felt. If you’re going through a hard time you tell your friend instead of ignoring the situation.Nayun could be better at picking it up that romi wasn’t feeling ok but remember they were young. The real problem was romi jealousy issues she definitely always felt like Nayun just had it easy.

I think based off the flashback, it sounds like Romi did communicate though. She even had a blow up, and based on Nayuns reaction, it was received with confusion and then dismissal. She never questioned any of it. Even if Romi didnt handle it maturely (as you mentioned they're young), as a friend, you would question that.

I know if a friend blew up at me like that, especially one you thought of as a best friend and went through so much with, I'd want to hear them out or at least call them out for being rude. Nayun just watched her walk off, never questioned it (assuming for the rest of their hs and adult life) and then greeted her like it never happened. Talk about rubbing salt on the wound.

Romi didn't communicate her feelings in a clear way which caused her to harbor bad feelings toward Nayun. Blaming Nayun for her life going wrong is insane Nayun isn’t a bad friend she's just not a good one either. Remind you that putting all the blame on Nayun is insane. It felt like salt rubbed in the wound because as time passed she hated how Nayun was doing better than her not because Nayun wasn’t there for her. Ive never felt that way about a friend ever even when they didn’t see what I was going through. All this justification for someone Thats obviously in the wrong is crazy.

Theres a difference berween unclear communication (romi) and no communication at all (nayun). I think the way you wrote your comment/thinking type is dealing in the extremes.

Is Romis jealousy bad and unreasonable to you? Sure, but it's also realistic. Ive never been an idol trainee, but if one person leaving changed my entire life trajectory, I'd crash out pretty hard. Especially if that was a best friend and she let me walk off without even asking what happened. Keep in mind Romi TRIED to be happy for nayun despite the inferiority complex.

Nayun for sure isnt a bad or good friend, but thats also pretty telling in itself. If I cant say my best friend is a good friend but also not a bad one, most people would probably question that.

Not sure what you mean by justification because im not saying Romi is entirely blameless in how their friendship fell apart, but to be fair she carried that friendship for years. People do have breaking points.

Everything you're saying is justifying her behavior, yes having feelings is valid but they become invalid once you respond badly. Nayun isn't expected to run up and make up with her friend after she blows up at her. I wouldn't even call blowing up at someone communication at all. You try to paint Nayun as the villain and say she's responsible for the hurt that Romi built up. When she's not responsible Romi is responsible for feeling jealousy and envy toward other people. Are those 2 realistic emotions yes but what caused those emotions is not the issue. Romi had been feeling like this before it's just all came out when she saw Nayun succeeding in life.
