Everyone has had a one-sided crush atleast once in their life and this drama will definitely unleash a stomach knot of nostalgia from that certain time. Now I haven't read the novel, but I really want to now because of how relatable the female lead was for me and how spot-on they managed to capture the raw emotions of unrequited love. This drama is also surprisingly realistic when it came down to it and the lack of major clichès was very much appreciated. Characters weren't just carbon copies of the same robotic personality with different faces and I actually came to fall in love with some of them. And OMG to the Only Yesterday and F4 references; those were brilliant! Sure.. it was kinda slow at times, but overall this was a great watch and I managed to finish it in 2 days. Totally recommend~!
