I unexpectedly loved the story as i waited every week, waiting for every week’s episode was fun because the story line was really chill though it involves the couples past relationships. Every episode gives me butterflies in the stomach because of their great chemistry! Their chemistry was really good. The drama also have cameo of some stars which makes it fun to watch. Got to be one of the best drama in 2020. Really recommended if you love chill storylines. I watched this because of Seo Dan and Gu Seong Joon of Crash landing on you but ended up liking Song Seung Heon!
