I came to the show right after watching together with me (the prequel which aired second). The first few episodes were good though it was an adjustment as none of the side characters were present for this season except Yihwa who was the shoes focus. The more I watched, the less I wanted to see. The side characters (meaning the friends) were awful and the villains were ridiculous. Everyone was silly and bordered in stupidity while the main characters (Cho, Yihwa, Korn, and Knock) all seemed serious. It felt like the show didn't know what tone it wanted. Whimsical and goofy or romantic. As others have said there is a mystery element and a plot twist. The twist doesn't miraculously make the show better but by the time I realized I was in too deep I wanted to know who the bad guy was. Korn and Knock are a bit stiff here since the actors weren't as comfortable yet, I assume. The chemistry is still there though so if you want to watch just for them it is a tough but sweet ride. For those coming from together with me just proceed with an open mind and some caution. This is a big step down from together with me but worth it to see more of the characters you liked.
