Hello. Pu Yang Bo gets introduced to the novel as the ML gets stronger and joins a faction. I think this will happen early in the Drama as he has a big part in the ML early life. Ok, now to the FL lead. Yes, she has very little early “screen time”. The first time they meet is doing a mission together. You can see this in the trailer when they are with a group. I don’t want to give a spoiler but he does find his parents on his own as events happen. Interesting fact, the novel says the ML isn’t great looking and his younger brother is actually more handsome than him, this is kinda important 👀. I think they are going to focus on the demon churches arc cause that’s how the first half of the novel finishes before he levels up big time. I hope I kinda answer your questions. The romance is a super slow burn in the novel but I think they will work it in more in the Drama. Hopefully his Lion and Snake uncles make an appearance, I don’t think I noticed them in the trailer. Dong Bo is super dope and he is basically OP early cause of his work ethic, I hope they keep this in the Drama.
