What a lovely, refreshing rom-com. It is almost a 9 but for the unnecessary break-up and a messy tail (see later). It is refreshing to see the cool, clever ML doing all the chasing while the FL is clever and bold but a bit clueless when it comes to dating. Not that she is ditzy, just a little innocent and happy-go-lucky. The chemistry of the OTP is very good. Not raw lust, just pure first love from two nice sweet characters. There were genuine LoL moments as well. The scientific approach to dating from the ML is sooo cute, not done for laughs like other dramas but totally in character. There are just so many cute moments during the first 2/3 of the show, it really brings on the feels. That makes the obligatory break up so much harder to take. Especially, when the reason behind the break up was so thin and weak. I'd call it poor writing, to be honest. We don't need that just to have the bitter sweet reunion later on (can't recapture the light tone for several episodes). I can do without the manufactured pain and suffering for our OTP, thank you very much. All the support casts were great. Strong characters and lively banters. One last thing, there are 27 episodes on Viki. The ending at the end of ep. 27 is not the true ending, a bit meh and half baked. The reason is that there is an episode 28 (26 mins long) on Youtube with eng sub which you must watch to conclude the series properly.
