This is one of those rare dramas where the cast, their chemistry, the location and the OST all comes together to make a perfectly fluff filled rom com. Yes, the story has some points that aren't entirely believable, but then is any story based on 'love at first sight' truly rooted in reality? I watch dramas for a break from reality, so I suspended my imagination for 10 perfectly made episodes and thoroughly enjoyed this drama. And now I have a new favorite japanese actor (Takeru Satoh), and a new favorite japanese band. (Trust me, the OST is amazing and you have to check out other songs by them, like Pretender).
If you saw the poster and were immediately drawn to it, then stop contemplating and just watch the drama right now!!
