The drama took a promising premise of time travel advice and turned it into a bland rom-com experience. The "future self" advice failed to build a convincing and compelling case with proper nuances. There was a constant disconnect between both selves character's narrative and motivation, regardless of the nature of time travel mechanics. The humor surrounding the main cast interactions fell flat, especially when both love interests were equally uninspiring. The initial attempts at romantic chemistry were forced and awkward. For this story to work, they needed to remove any love triangle/square and solely focus on the main relationship to give some justification to the existence of "future self" and to build a stronger bond which would bring with it more emotions, higher stakes and a bigger climax. The twist in the last 2 episodes was a sad attempt trying to salvage what's left in the drama to bring some kind of climax for its finale. It's a drama that might leave you feeling like you settled for instant ramen when you were hoping for a gourmet Tsukemen. The sad thing, I wasted time, electricity, and heat encoding its BluRay discs just to see it end up this way.
