from what i’m seeing, his personality always seemed to be child-like, particularly to someone he’s strongly attached to like taehyuk. he just has a cold demeanour to anyone he doesn’t know, i think. him regaining his memories may have contributed as well, though. like since he reremembers how his relationship went with taehyuk back then, he feels more comfortable expressing himself this way. i’m not sure, but just looking back, it doesn’t seem to be thaaat drastic of a change.
this was always his personality but he turned mean and cold when Taehyuk's past life died and hyo-un went on hybernation. he was also mean to taehyuk bc he was looking for his mate and didn't want anyone else, but now that he has his memories back, he remembers who taehyuk is to him and is back too being all sweet and puppy-like
He just went back to his usual self. The one we saw first wasn’t entirely him because he didn’t have his memories. He knew there was someone that he loved but he was mad with himself for falling for someone else. In the last chapters (their past) the author shows how he was when he was with him, and he is acting the same way now.
Am I the only one confused on why the dragons personality is completely different? Its like he reverted to when he was a child and hes even calling the mc sir. Idk if he lost his memories too and only remembers the past reincarnation of the mc or if when he regained his memories he lost his current personality but it's weird to see him like this
