This story was really slow at the beginning. I literally stopped watching several times and kept going because of all the good reviews. But it really picked up around episode 15 and I just kept watching.
The only part I didn't understand was Suying's obsessions and her refusal to see that she is unhinged. Because of her obsession with a man who didn't want her, she was used to attack the dragon who was ready to marry her. She then justified her actions by calling him and all demons evil when they were just existing. And everyone was like, yup let's agree with her. No other human was like, wait didn't you attack him, how is he evil? Because of her obsession with the man, she killed his wife in front of him and was mad that he still didn't want to be with her. Everything she did was supposedly for the man but she just couldn't get over the fact that he didn't want her or that the dragon ultimately got away.
These people ignored the fact that the whole family was crazy and just let her do whatever.
And the Phantom Lord, what was wrong with him? Why was he giving off hunchback drag queen?
