Skipped a lot of scenes; Song Kang is the main character but his screentime was as little as an infant's thumb. The plot is all over the place and unnecessary. They could just make Lee Do Hyun come back early off in S2 and focus on both that and the military (+cause/origin/cure of disease/virus) part rather than letting the viewers focusing on watching a kid with mommy issue majority of the time. S1 is a lil bad already, considering how they change the webtoon's plot so much but this is hell lot worse.
