I don’t like yuijin

Idk man...it actually is pretty realistic and makes a lot of sense in the context of Yujin's deeply traumatized yet untreated ass the man has literally showed throughout this whole story that he has gone through life relying on unhealthy, self-sabotaging, avoidant coping mechanisms (i.e. sex addiction, aimlessness, fear of commitment) combined with his low self-worth (a common result of childhood abuse/neglect), which is why he was just now barely becoming able to accept Aaron's love....so it makes sense that his avoidance would kick in cause his coping mechanisms are subconsciously-developed trauma responses that attempt to "protect" yourself

Ngl when those kick in, you kinda lose the ability to think rationally and it's mostly a conditioned response that's hard to stop (something about the primitive brain taking over in survival mode cause you're triggered and stressed the f out, according to my therapist lol) your brain is just triggered to do what it's been wired "incorrectly" to do to "protect " YOU and you can't really think of anything/anyone else :/....

This is why i believe you can't truly love someone right until you learn to love yourself (and get better mental health) but yujin is far from that

You’re right, and the reason I’m so upset with him is because all he’s doing is hurting himself and Aaron. I want them to be happy, which is why I was so frustrated. But the root issue is a learned response, and I can’t truly blame him due to his upbringing.

Love yourself first. That is a very true thing. He’s not ready.
Thank you for taking the time to respond

Totallyyy... I mean people can def overcome their circumstances and start being able to make better choices (and hopefully Yujin will eventually
