ah, the age old grumpy x sunshine trope! you know em, you love em! this was actually one of my first watches and it also introduced me to now one of my fave kpop groups, namely The KingDom (formerly called KINGDOM) because they wrote one of the songs on the soundtrack (Traffic accident by DANN & MUJIN from TKD).
but back to the actual series. this series was a great introduction to BL for me! it's cute and calm but also has it's obvious heart fluttering moments and made me root for the couple. the characters were endearing though a little predictable but then again the whole story setup is quite predictable: the mc meets the male lead and forcefully befriends him and then slowly falls in love whilst also trying to hide his ulterior motives and then comes at the point of where he needs to decide between his original goal or his new love. the story is enjoyable but not enjoyable enough for me to rewatch it if i'm honest because to me the acting, editing and pacing could've been better especially from the main couple. but for a beginning bl actor i think gongchan did pretty good! the second couple, dowoo and won tae min is is what really stole my heart. the tension and the drama between them was much more enjoyable to watch because of the comedy and the history of the characters (but the acting was also better).
the production value was great but i havent seen that many k-bls so i cant really compare.
so would i recommend this series? yes, if you just started watching BLs and want something straight out of a romcom or just want to watch something that's light to digest :)
