the cast and their acting was amazing but i'm gonna be very honest and say, the story just got worse and worse as the episode went by. they made it so complicated by making the main couple and even the psycho killer be able to time travel. the romantic scenes lost its spark for me because 99% of the time i didnt know who's who. it icks me to think that junhee (or was it minju? lol) might be kissing somebody else that isnt her lover which to be frank at episode 10 i dont even know anymore if it was yeonjun or siheon that she fell inlove with in the first place. i get it that maybe they were going for the "even if we're two worlds apart we will find each other and love each other" trope thats why both junhee (minju) and siheon (yeonjun) can time travel but when it was revealed that the psycho killer can time travel too and on top of that chan hui wasnt actually the killer but actually it was chanyeong his little brother who happens to look exactly the same as chan hui even if they arent twins???? jesus christ its all just nonsense at that point. anyway, the ost gather my tears by seo jiwon was good tho, i loved it. also, i didnt watch the taiwanese version so this opinion is solely based and about the korean one.
