The pace is kinda scared me ngl they keep the pace quite on par with the novel, just a bit faster but pretty much acceptable. I really hope they would get going like this until the very end and not suddenly change the pace in the middle of the story and cut a lot of scenes so yeah, I agree with you that this is going to need at least 150+ chapters for it to stay true to the novel

This next part with Seung is going to be elite!!!! Every time they bring back a side character it's amazing. I seriously hope they'll keep it true to the book.
I can't imagine how many chapters this series will have but I hope its in the 150s+. It's the least FTSIA deserves. I can't imagine how they'll condense it any less than that unless they cut out a bunch of stuff.
