This story isn't really filled with dramatic plot twists but I enjoyed it.

All of the main characters are working in the industry but mostly behind the scenes like writers, directors, marketing, composers, and managers. (I think Somin is the only supporting character that's a celebrity). I learned how Kdramas are created in this drama because it showed the step by step process of it since the main couple is a writer and director creating a drama together. Sometimes I wonder if this is really based on the author's personal experience lol.

I really love how the side characters started low (?) and started to develop in the next episodes, making me more interested in them. There are a lot of side couples in this drama. I didn't pay attention much to Somin's character and story at first but I started to enjoy seeing her relationship with her manager and her life as a celebrity. Even I find Jinjoo's ex boss funny in the later episodes. But Director Kim Sangsoo really stole the show. He only appeared midway and I wished we got to see more of his story and character. I really liked his relationship with Eunjung.

[ SPOILER ]
I think I might be the only one that's glad Hanjoo and Jaehoon didn't end up together because I can't really ship them because Jaehoon's still with his girlfriend. I felt uncomfortable in their relationship (If I were Hanjoo, I wouldn't get too close to a guy with a gf or If I were the gf, I'd be jealous if my bf's getting too close with another person who also seems to like him).
