*Storyline: Main story revolved around recently popular motive - age gap problem. And it's based on thing that never disappointed me so far - childhood friends;p Let's be frank - that's truly classic rom-com recipe. Comedy, foolishness, chemistry and comedy once again. Also side stories were great - they were so good, that they could've made a dramas for themselves. *Actors: Every single actor made it into perfection. Writers made great work in this aspect. (everyone had one or more memorable sentences. That was cool.) *Music: So good and so Sung Joon, and... I would give 20 if I could. *Overall: Mixture of nice colours, perfect music, sweet atmosphere and feelings. It was definitely the best "I need romance" for me (so far;)) (To be precise, I rated it so high mainly because re-watch value - I really rarely re-watch anything and this drama I will;)) ~Cheers! (and I apologize for grammar mistakes;))
