Honestly, overall this is a good drama, but it definitely felt like it dragged on more than it needed. I did end up finding myself skipping some parts forward, specially because there were some characters I just couldn't stand. One of my favorite things about the drama is actually the OST. There were some characters that made the show more entertaining as well, but there are still a few points that drag the story down other than its length. One of them is the sick "love" relationship, both on Runyu's part and the main characters. Their obsession with each other was just tiring and at some point became straight up annoying. Another kinda bad thing is the awkward acting of some of the characters, but honestly you can look past that. Overall I would go back and watch some parts again for sure. Would only recommend it if you have a lot of free time to spare.
