If you get the chance and have the time, I highly recommend you read the novel. It's over 170 chapters, but it feels like a quick read. If you're a member of NU (abbreviating out of laziness) then you can access a link to the TL. There's way more emotional depth to the novel than the comic. Both the MC and ML's inner thoughts and all the history and drama. It's a 20/10 read IMO.
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.
Did they bring in back all ml team, or only 1?
All of them
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
