This show was really good it kept you on your toes and had unexpected surprises. But there were things that were mentioned that felt like it just became irrelevant after like junhee’s swimming fear. And once kyungjun died the show felt more plain and kinda dry. Then they ending was very unsatisfying because it felt rushed and the parents whole reasons was honestly kinda stupid because what does the whole class have to do with your daughter’s death then saying yoonseo just watched her die (she clearly didn’t) it didn’t really add up. Personally the only way I can be somewhat satisfied with this ending if there was a S2 or more episodes where they actually get free. But it’s still worth the watch because the cast did a flawless job.
