I hate myself for having unrealistic ideals about ukes/MC’s personality, that they should be kind, humble, selfless. So seeing Jun especially his inner thoughts made me uncomfortable, betraying my expectations. Yes, I was wrong for thinking like that because actually Jun is so real. If I were in his position, I might feel and act the same way he does. Jealous when my crush was interested in someone else and didn’t want them to grow closer.
Is there character development though? I just read chapter 5.
I mean, it's your preference. I don't really have any problems with the mc, as long as they aren't a pervert, or have any controversial personalities/traits, or just straight up a Mary Sue. I like an mc that grows along the series and either overcomes their flaws or accepts their flaws, then shows the process of how it happens.
Usually, I see that kind of personality in supporting characters who act as rivals to the protagonist—you know, the two-faced types with hidden agendas? Perhaps I’m being too empathetic toward Taesan. That’s why I find it hard to accept the way Jun treated him—given that there was an ulterior motive involved.
Can’t wait for the official translation to complete.
