A light-hearted series full of the usual rom-com clichés, but everything has been put together so well through impressive acting, and impeccable comedic timing that the clichés become a necessary part of the show. Kim Sejeong owns every character she plays and this was no exception. It's always better to watch a series when everyone understands the assignment. Basically, it's frustration-free. I would revisit this again and highly recommend it to anyone who enjoys a good rom-com. This is at the high end of its genre.
