Initially, I thought this kdrama would be a refreshing story about depression, disability, and fate. But of course, it ended up being just another kdrama with a meaningless serial killer driving the plot. Honestly, the serial killer is my biggest gripe about this series. He's a nobody antagonist who came out of nowhere with a grudge against the leads for no reason. They spent zero time fleshing him out, with no mention of his motivations, backstory, challenges, nothing. He's simply a plot device driving the couple apart and back together. Not to mention how they quickly killed him off at the end and then boom happy ending everyone's happy. However, Im Sol and Seon Jae were delightful to watch, and their chemistry was amazing. The comedic moments were well executed, and their story was touching. But I can't help but feel the story could have been so much more. If they had followed through with their setup: a story about a disabled woman and a depressed idol, where she goes back in time to save him from himself, the story would have been so much more impactful. I really don't like how they just discarded those plots. All of Im Sol's struggles with her disability and Seon jae's struggles with burnout and fame are just thrown out the window in favor of a generic serial killing taxi driver. If I rewatch this, it will be for the couple and the comedy aspect, because the plot really disappointed me.
