I know I'm late to the party but I finally decided to watch this series too. Usually when I watch a hyped drama I'm getting into it with low expectations to not get disappointed, but with this show I stayed away from reviews and comments to not spoil myself and I'm glad I did so. I just finished this, I binged it in 3 days even if my very tight schedule was not allowing me to have too much free time bit I couldn't help myself, and I must say I got hyped quite fast. I highly enjoyed it. This is one of these dramas that I wouldn't mind if it had 10 more episodes to binge on.
It started quite cheesy and with some cringe moments, it had a lot of plot holes, but I have to say that I loved all the bits and moments in it. The cringe ones, the great ones, I cried with it, I laughed with it, overall I can say this is one of the best romantic k-dramas I ever watched. Honestly it should have a higher rating than many others overhyped in MDL have.
All in all I warmly recommend it.
