I'd argue that disappearing for a year isn't still enough excuse (cuz there's no excuse) for how Aaron is treating Yujin.
Aaron may love him, but his love comes with obsession and possessivity. He's not just pissed cuz Yujin left without a word, he's pissed cuz what he thought was his possession got away. He didn't want payback, he wanted to reclaim him, and he did (at least his body) in a way that Yujin clearly hated.
Also I believe Yujin still calls him Hunter cuz he doesn't trust him. He probably never really did.
Honestly, yujin started this by ditching him for a whole year, And aaron was brutally hurt for being completely blocked away without any reason whatsoever... Now Aaron wanted payback by messing yujin up, right? This chapter was so hot ( ◜‿◝ )♡ but when yujin said "leave me alone, I wanna go home"?... Bruh Aaron my man....I think u went a little too far with the punishment... U could have been a lil gentle with the huge throbbing monster of yours ಥ‿ಥ...
Althooooouuugh... Yujin STILL calls him HUNTER (Aaron hates that) and STILL refuses to admit he misses him! U two are so stubborn!! Pls kiss and make up soon
