Its worth reading though, I didn't like it at first, and the cover wasn't attractive to me so I always skip it, but someone recommend it to me before because they said it was funny, the plot wasn't boring, and it was fresh read, because some plot are recycled too much I was getting bored but this one is different.
SOFT SPOILERS!!
Yes, with this kind of genre it's obvious that the MC does get strong along the way lol BUT what makes this novel interesting is that
as the story goes by, readers will realize it's not just about the MC's strength and lungs anymore. It's more about how this green alien will navigate his life in earth. Learning more about og!kim giryeo, discovering a plot twist about one of the main cast's identity, and getting a more detailed reason as to why the green alien actually regressed (and how it's connected to earth). The first few chapters (Chaps 1-3?) is really important, it somehow spoiled everything that built this novel but at the same time it didn't. Rather it "simplified" the most important parts of the story and we're gonna learn more about this soon!!!

im at ch21 rn, and im really not finding this that interesting, can yall tell me what happens later on? like, will his lungs get better or something?
