I have a really high expectation for the drama because it received so many great reviews. it doesn't disappoint me but it didn't quite fulfil my expectation as well. pros first, since this is a police investigation drama, the cases must be interesting, and it did. the cases were good and keep me guessing what will happen next. the acting were amazing, every cast did a really great job in acting their roles. the romance were subtle which is good, because i feel like if there's more than this it will feel kinda awkward. okay the cons, the time travel wasn't stressed enough, i feel like the present wasn't talk about enough. the whole, is this a reality or a dream, means the present wasn't supposed to be completely cut off but they did. the chemistry between the team is really important but i can't feel it here, and the bromance was meh as well. the storyline kinda feels draggy in the middle. all in all, it was a decent drama for me
