I dropped this drama after finishing the 18th episode. I had surprisingly no problems with the plot and thought they executed the age gap at the beginning pretty well. It didn't feel weird when the FL and the ML got together because you could tell she matured. The thing that drew me away from this drama though was the FL. She's portrayed as super innocent and her personality is just meh. I found myself really bored with her character. She always had this look on her face when he did anything that made it seem like she didn't even like him. The plot was more cozy than exciting so it was pretty much the character's job to carry the show but the FL just missed the mark for me. If the FL had more personality I could've seen myself really enjoying this drama.
