This was a trademark k-drama so further review can't really be considered spoilery as it happens in basically every drama. However, If you can live with or it doesn't bother you that: 1. The good ones, as usual, get all walked over by bad ones who don't get any punishment or retribution, everyone's all friends afterwards instead of getting burned alive. 2. Drama adds totally unnecessary drama just to drag it longer and so it certainly dragged the last 3 eps instead of flowing nicely (thou not that the added drama was draggy, it went well... but could've done without it) 3. The completely unreasonable break up. I'm not even gonna comment on that one. THEN if you can overlook those 3 above, I would recommend watching it cuz I truly enjoyed Heartstrings up till end of ep 12 when noble idiocy took place and it annoyed me to anger. Had someone warned me of it I would've been prepared & not as angry, could've just rolled my eyes and munched on popcorn while cussing them XD It was fun, the music was great & the main leads were great :) Even with the trademark wide eyed & stiff act from heroine whenever kiss is involved. #3 has now made me rather vengeful, cuz I don't even remember which drama it is by now that has all the 3, well, 4 if we count stiffness too, trademarks that could totally be done without as it only ruins the drama for me. I really wanna find a drama where for once when the idiot who breaks up with their loved one for their own good aka so that loved one could achieve whatever, they wouldn't get back together and the loved one would find new love & live happily ever after, while the idiot who decided to break up for the better & let go instead of holding on & not letting go, would then wallow in misery. Would totally serve him/her right. So yeah, while I liked the drama, the #1-3 has ruined it for me and not gonna watch it again. Goody two shoes are overrated, stand up for yourself and don't be a well meaning sacrificial idiot either! If they had left out the mess and had this ending, I would've re-watched it again, but now it's barely worth watching once. Plot was good, actors did good, music was good too, so I'd say watch it once and see for yourself. At least till ep 12 and if you can tolerate not breaking your laptop (which I somehow managed) watch the last 3 eps too just to see them on screen or if you're already used to this kind of k-drama or maybe if you like the added drama :p And also watch it cuz Shin really was a great boyfriend, for that alone it's worth to see ;D
