I mean she jumped to conclusion without talking to him first. Why is she mad? Maybe he is ...

Yup, lack of communication. I think she was so eager to jump to conclusions since- MAYBE she was insecure during the relationship and overhearing that conversation must have affirmed it. Still, should have communicated. Both of them.

She also doubted the fact that he loved her throughout their relationship because she knew damn well what his personality trait was before they dated, so she already believed she only managed to get with him because she got so close to his family. She’s basically just upset about the fact that her own suspicions were confirmed and that his love for her isn’t inexistent, it’s just different.

because iseon got into the relationship, initiated to start a relationship with her knowing damn well bro couldn't reciprocate the romantic feelings she had for him. I figured out that he's aromantic but getting into a romantic relationship knowing yoomin had a fat crush on him was messed up, and really unfair for yoomin. he did changed cause he realized he lost a gem but it's too late bruh she already ended things

Initiating a relationship because you like someone and hope for more isn’t wrong. What’s wrong is never sharing the fact that his love wouldn’t go any deeper for her than it already was. However that doesn’t mean his feelings weren’t genuine or worth her time. He intended to build a life with her because he wants to spend the rest of his life with her. Still, blaming one person for the failure of a relationship is also wrong. It’s a two-way street. Yomin only cared about what she wanted, so she made sure that she was around his family long enough for the natural next step to their relationship to be for them to date. She acknowledged this even as she agreed to date him. However her hope was that his feelings would deepen. She didn’t realize they never would. And he didn’t change either. He feels for her now what he felt for her before. Only difference is he’s more vocal about it now.

yeah but shouldn't starting relationships should make you understand the efforts you have to input it in order for both parties to be satisfied? and if his feelings for her were truly genuine then why did yumin feel like she's the one putting effort and caring too much about the relationship? i do agree they were both selfish in their own way but it's ridiculous how iseon initiated the relationship as a more transactional feeling than out of genuine feelings. it's also too late for him to say anything especially if he's expecting anything for her. tbf the author made it so they did a poor job at communicating so ggs!!

- At the start, it makes sense for not everything to be told, it’s really the fact that they dated for YEARS without him ever bringing it up that’s wrong.

- While Yomin’s feelings are valid, to say that she felt she was the one putting effort is wrong. She herself couldn’t say he was actually bad to her because he dated her with sincerity. However, Yomin felt that she was the one who cared too much because she knew she manipulated her way into that situation. It was specifically because she became so attached to his family and then to him by extension that dating became the natural next step to their relationship. She was in doubt the whole time because even as he asked her to date, she sensed that he hadn’t changed since the first time she met him. She was simply hopeful that it would change. She walked into that with both eyes opened. Still, that doesn’t negate the fact that his feelings were genuine. The problem here is that their level of love for each other doesn’t even start and end within the same spectrum. So while she’ll never be able to feel him love her the way she wants to be loved, it doesn’t mean he doesn’t love her.
