This one is my all-time favorite! It marks the beginning of my romcom journey, setting the standard and fueling my obsession with romcoms. It's cute, heartwarming, and inspiring, with a simple yet captivating story that doesn't require much brainpower to follow but still manages to make your heart flutter. The love story, friendships, and family dynamics are portrayed in such a relatable way that I absolutely loved it. The chemistry between the main actors and the supporting cast is overflowing, and their acting is magnificent. I have no complaints, except I wish the show was longer. Everything about it is perfect, even the OST slaps. I've rewatched it 5 times and never get tired of it. Maybe I'm a bit biased because I'm a fan of Lee Sung Kyung (fl), but I truly believe this is the best romcom K-drama. If I had to pick just one K-drama to watch forever, it would be WFKBJ!!!
