If you don't understand his character then maybe you should read it again..he never claimed to be a greenflag. He was always only nice because he loved Yujin. And all Yujin did was lie and leave. And their relationship dynamic didn't change much as well. They used to be like this before too but this time without Aaron's sweetness. And Yujin felt that too and he realised he lost his home again.
Oh I never said he is greenflag, if anything I know how his heart is basically a hard rock placed in his chest cavity. him getting this possessive and it manifesting in such ways is what I dont get. Cool calm collected and strategic is what I'd expect from him, even in the matter of love. What he is doing shows no strategy nor a clear end goal, like what are you doing all thia for? I was hoping this chapter would show glimpses of why, but I still don't see it. "He's lost his home again" ouchie
Do you realise Aaron suffered for a whole year? It was Yujin who made all that promises with flowers and left. Aaron was a victim since childhood for things that had nothing to do with. Yujin lied, betrayed and Abandoned him. How do you even expect him to stay calm and collect? His only goal was to find Yujin anyhow. That's why at the end of this chapter Aaron stopped even after saying those eyes wouldn't work on him and left to get water. This is just your bottom biased opinion talking. Some of y'all acting like Yujin is some fragile y/n. And this was not grape because Yujin had no problem with the sex.

Honestly I dont see where Aaron is coming from, this really doesn't make sense for his character and I can't understand what he us wishing to accomplishing from keeping him imprisoned, like what's your goal here? Yk how yujin operates yet you pull this shit move? Make it makes sense.
