And why do I feel like art style become more bad in the starting of season 2

yeahhh! it got kinda bad but then it started improving. when s2 first came out, a lot of people noticed the style changed a bit. it was suspected that maybe the author had changed styles and had gotten used to drawing older characters bc of the work they did in the haitus (sheeps mask) so the boys in litc has longer faces and stuff. lmao i remember there memes about it too!

Planning to read this. Sooo what is the age difference between them ????

They aren't father and son. Nanmu dated Pil-gyun's mom for a hella short time and was the only adult to ever treat Pil-gyun like a human being as a child. Pil-gyun's feelings developed into obsessive love for Nanmu after all the trauma he suffered and that's how their relationship starts when they reunite as adults lol
I really like stories like this
