I’m confused. Why is Eunsung angry? Because Taegun had a relationship before him or beca...

i feel like he's just angry about the guy who was possibly planning something bad again to taegun

I'm wondering the same! It's not as if Eunsung only thought Taegun and the other had a relationship and it's jealous now. He already put two and two together about what actually happened, and he probably feels that the mf is dangerous, so I don't get his reaction and it kinda pisses me off how he's taking in out on a vulnerable and confused Taegun who keeps going thinking Eunsung is mad with him :(

Yes exactly! That’s why I’m so confused. Like I get you can’t always control your emotions but it’s not fair to take it out on Taegun. I was so happy last chapter when Eunsung showed up and whisked Taegun away before that horrible guy could mess with him. I was expecting him to be nice and considerate of Taegun and now I’m just annoyed. I dunno, I guess I’m just feeling super overprotective of Taegun and want to wrap him in a warm blanket and keep him safe. Hopefully next chapter will clarify things more because otherwise I really do love Eunsung

By the end of season 1 we learned that Eusung had some unresolved issues from when he met Taegun for the first time, but idk... I can expect shitty, selfish and irrational behavior from most of MLS in bl, but Eungsung seemed to be built differently--and I guess that's why his reaction feels so off, even more because Taegun is explicitly showing he's anxious about it.
I'll give him the benefit of the doubt tho. I won't give up that easily on how much I love them both. I just hope the next chapter clarifies what's happening in Eunsung's head :(

Yeah exactly. I was expecting something different from him so his behaviour is confusing me. I just don’t want Taegun being mistreated again and I know Eunsung is nothing like that other guy but it bothered me.
