I think there’s more to his ptsd than just his mother. I think it explains how he has a complicated relationship with his father but his actually anxiety and trauma seem to hint that he has a major event that was linked to him performing and singing. So I don’t disagree with you but I think we will learn more of his backstory.
(Or I’m misremembering things. Completely possible.)
Yeah, I don't doubt the complexity of how his personality has been affected from what he's gone through in his family. I'm only expressing that to me it doesn't feel like a strong plot point based on how Yujin is depicted when making these self-sabotaging decisions, which lacks depth imo.
Even in the later chapters of season 2 there were still instances where Aaron was painted as "someone dangerous, who could crush Yujin if he wanted to" and Yujin didn't speak a word to refute that at the time. That's why I find it confusing what the author is trying to portray and how the characters are being used for the plot to advance in certain ways. All the explanation needed for Yujin leaving like that is his ptsd, so why add such implications, if not to superficially up the dramatic conflict that's to follow? I feel like Yujin's trauma is being used a little too much like a plot device instead of something to be explored. It's not terrible, but again it leaves something to be desired if I'm trying to care for the character.
Ngl, I'm still excited to keep reading, but I think Yujin running away - especially when Aaron has somewhat aired out stuff about his father - is somewhat a weak plot?
The man genuinely wants to be with him, isn't afraid of ruining his image or going after his deranged father. Even with his anxiety and ptsd from what happened to his mother, surely Yujin can see that he's not actually "helping" Aaron by staying away, nor can he truly believe that Aaron will suddenly want to live some stereotypically "normal life" like getting married to a woman amd having kids.
He KNOWS he's not gonna just pretend this never happened and put on a mask to satisfy society's stereotypical expectations. So this all points to Yujin using Aaron as an excuse to leave and hide, bc staying in one place, committed long-term with someone triggered how he thinks he's undeserving of a stable, loving and fulfilling life. But I just don't buy it from how he's depicted.
Maybe if they'd shown Yujin be far more affected by his trauma and highlight the irrationality of his anxious train of thought, I'd be more invested in it. Now it just feels like a superficial cat and mouse chase, just to easily add drama, draw some destination locations (is Yujin gonna tour Europe or village-hop in England?) and give us a disheveled Aaron.
