I'm not a fan of romcom, tbh, but CLOY is an exception! the humour is best, the chemistry is heart wrenching, the ost(s) are top tier. I find myself laughing, crying and smiling like an idiot. I always pick dramas like K2 and Vagabond, but this one... I think you will regret it if you miss the show. Once more, Hyun Bin and Son Ye Jin have the greatest chemistry ever. I love this.
plot-wise, it's 3.5/5 but all the components in this drama cover all the flaws.
