The story is promising until it becomes unbearable, beginning with some interesting facets, highlighting issues of the wheelchair bound people, parasocial fan culture, mental health struggles, time travel and the rules of this particular version. Once Sol and Seon Jae meet, there is no chemistry though the engaging mystery of the lead figuring out her situation and how it works kept the pace going, but soon there is clearly not enough plot to to sustain 9 episodes, let alone 16 episodes of hour+ runtime because it just relies on tropes to pad out the runtime with all of the interesting set up just abruptly ending, unexplored and unaddressed. What the drama became was like the writer is actually desperate to write a comedy and is also really bad at it. There are so many shouty scenes of endless misunderstood moments, withholding information and intentions, stupid testosterone contests, side characters bickering that go on forever.

The acting of the leads aren't good enough to elevate anything either. The second lead Tae Sung is comparatively better than the rest and the character is the only one that has growth and change throughout the story which helps to make his quirky scenes that don't involve the inane one upmanship with Seon Jae, actually funny. Sol has always acted immature even as a 34 year old adult and her entire focus just revolves around Seon Jae when she goes back in time. She doesn't get to have an substantial moments to develop her bond with other people like her family who were also facing some serious problems like her mom's health, her grandma's eventual mental decline, or even her friend and future sister in law. Everyone is just a comedy bit. Even Tae Sung with his father when he rushes to the hospital after his dad was nearly killed by the escaped serial killer, the show just leaves it at a comedy bit. Seon Jae is actually even more immature as a 34 year old in all iterations of his life and also doesn't have a single serious moment with his father. The leads have no dimension in addition to no chemistry, so their relationship has no weight. Truck sama wiping out the serial killer is the ultimate lazy conclusion. They should have had Sol behind the wheel at least. The show hates depth and characterization. The sky high mdl rating as of this writing confounds me, there are dramas that are way better that don't have anywhere as near high ratings.

I do not recommend this drama. If you want a well done time travel back to high school plot to save a guy, watch Love for Love's Sake.
