Based on how many events we still haven't seen yet, this will be a long ride for the back story
Estio is still just a baby dragon and really should be with his father. He still doesn't know the ways of the world or who to trust while the only person who can teach him to protect himself and to use his powers is his father. He doesn't owe the guild anything, but unfortunately is a very caring soul. Hopefully he is able to learn before it's too late and is betrayed by those he trusts
It was already a broken relationship long before this point. She didn't feel loved for years and just accepted that was all she could have. She wasn't able to be honest about hearing the phone call either, showing the lack of stability, trust, and communication in the relationship. She should move on, but it makes sense why she will struggle knowing there was something that 'could' have made it work.
The ex boyfriend's crash out was valid tbh. His actions weren't the best, but seeing your girlfriend for a year who didn't want to do anything sexual with you immediately getting together with another guy and having sex, on top of the fact he heard from someone else that she told her friends his d*ck looked gross would really suck. It doesn't excuse his harassment, but he had every right to be upset here and she made it seem to a certain extent like he didn't and was weird for being upset even before he harassed her
I still don't understand why she left. She left because she was dying, but then sent a letter for the ML to search for her because she was running from someone, but she wanted him to chase her. None of it made any sense. I don't understand why she came back or needed to run in the first place especially when she apparently knew she was healed
Every plot twist is just ANOTHER person screwing over the MC. Hangyul can't catch a break from all the betrayal. I'm mad at everyone right now tbh except the MC. Too many people have it out for him for no reason, even his own parents. I think I'd be happy if the ML was no longer able to act due to the curse, since it wasn't his right to be famous anyway.
From a leadership standpoint, why wouldn't the king support Raymond? Like I get that politically it would look like her supports him as a potential future ruler, but for a person who has done so much for the country and to still leave them in debt and not help him to continue to solve the issues of the Bay Region makes no sense. You can support him in ways without making it seem like he is a future kind prospect.
