most of the actors are overacting all the time, too many filler, too many "coincidental" scenes between main characters (falling into each other,...). Additionally, there are many details that are given only once and are not repeated or developed or explained (the first time the male lead dies of depression - why is he depressed?, the scene where the female lead discovers that
her mom hides her illness - has their relationship changed?, the female lead can escape the fate of being crippled but find it difficult to save the male lead?). In particular, what annoys me the most is the pair of supporting characters (the female lead's brother and best friend). They're too loud and don't really contribute to the main story line
