I care about this drama so little I can barely manage to write a review. It was a slog just to finish it, even though it's pretty much just the length of a movie. Regardless of my initial appreciation of the chemistry between the three friends, I felt absolutely no connection with the female lead and saw no clear character motivations brought up among them. There is frighteningly little real conflict or stakes, which wouldn't be too bad if it weren't for the complete lack of effective comedy throughout. Simply put: I didn't care. I didn't care about the characters, or their connections, or the unconvincing goal to return to the past (none of them seemed quite attached to it anyway). Whatever romance there was felt forced and undeveloped, and the female lead basically had no compelling character traits or motivations or flaws or... well, basically anything. I don't have too much against the acting or production, but I really just couldn't care less about any of it. I do not recommend this drama.
