He behaved like this anytime he was out of it so it’s not too strange in terms of the story. I do miss him being a touch cold too though. I found the difference in their personalities really fun. But now it’s just Taehyuk back to being a little shit and Hyo-un is kinda just… there?
I wish hyo-un kept some of his old personality before he regained his memories? hes behaving too childlike for me
