a disclaimer, i didn't watch the original chinese drama. this is a super super supeeeeeer light drama (or web drama) and a very cute, bubbly and fun one. personally, i kinda enjoy it since watching it ongoing with only 20 minutes each episode wasn't that bad. the early episodes (school part) was a hit or miss for me since it wasn't really cohesive and it was like an event after another. so some episodes were super cute and very funny, some were just plain boring. the adult part was better since it was cohesive and i was excited to watch next episode but that part was so short, i guess it was only from ep19. their friendship was my favourite part as well as the osts!! i love loveable by kim jong kook a lot and sinb version was great too. storyline wise, don't expect anything, just accept that this was super light non-cohesive fun drama, and that's how i managed to enjoy this. the acting was okay but sometimes i kinda feel like so ju yeon cuteness were a little bit forced, other than that, it was okay.
