ah there's a comment here that complains about the build difference in the two, something that usually happens in korean bl manhwa... i get it too, i was gonna agree with the op until i got to the later chapters... in this case it makes sense bc Jiwoo was sick and was hospitalized a lot, he couldn't even do any extraneous physical activity until the transplant. pretty sure that delayed his growth... anyways i got hospitalized once in highschool and i lost too much weight that i couldn't regain even after much effort
