Y'all really don't realise it isn't realistic for him to just move on so easly. He does want to part from the toxic relationship, and he probably will by the end of this comic, but for now y'all really need to understand that toxic relationships are more complex, given why so many people in real life still stay in them after long periods of time. It's not easy to fall out of love when it doesn't happen naturally, or with someone you've cherished for such a long period of time.
And he is most likely to move on soomer or later in this situation, let's be honest.
Ok, this is a slight explanation for y'all confused souls.
Back like I think 600 years ago (or more) Yoosung and Yooshin were two twins of the Royal family. For the country to gain a God, Yooshin sacrificed himself to become the yellow dragon. This meant that Yoosung took over the throne, becoming Emperor Yoosung from 300 years ago. When the gods teamed up against Yellow dragon because of the mountains, this resulted in Emperor Yoosung's death, also yellow dragon's brother. Yoosung has been dead for 300 years and has no connection with the new Emperor dude, forgot his name
Unpopular opinion but this story would've been less tangled if either Clark didn't start talking to Alex or the dr handed Alex in. Murder is murder and all that Clark fid was endanger more people, including himself, and worsen Alex's mental state, including making him quit his psychiatric sessions. Honestly Clark's been playing too much with everyone, as the dr mentioned in a chapter :/
I feel like those two's relationship in the past must've been so toxic I can almost taste it
