Good but the second half was unnecesary
TL;DR:
A heartfelt time-travel romance with strong emotional moments, good acting, and a compelling twist — but the second half drags with unnecessary plot padding. Still, it’s a memorable ride.
The drama begins with Im Sol, a girl in a wheelchair who lost her will to live after an accident left her disabled. One day, while listening to a radio talk show featuring a rising boy idol group, she unexpectedly gets through as a caller. The group’s leader, Ryu Sun-Jae, gives her heartfelt encouragement — a moment that becomes the spark she needs to find purpose again. From that moment on, she becomes his biggest fan.
Years later, Im Sol finally gets to meet Sun-Jae in person. But mere hours after their encounter, she’s devastated to hear the news of his sudden suicide. In a desperate attempt to see him at the hospital, she races there in her wheelchair, only to fall into a small river — along with the special watch she believes belonged to Sun-Jae. When she reaches for it, something strange happens: the watch “glitches,” and she wakes up in her high school years, in the past.
The rest of the story follows her attempt to change the past and save Sun-Jae from his fate. Along the way, she reconnects with her younger self, learns more about Sun-Jae’s life before fame, and discovers that he once loved swimming — until an injury ended his dreams. She tries to protect him, hoping that saving his passion might also save his life.
Then comes a major twist: Sun-Jae already knew Im Sol long before she knew him. Not only were they childhood neighbors, but he was the one who saved her during the accident that changed her life. While Im Sol always saw herself as just a fan, Sun-Jae had loved her first — quietly and selflessly.
Eventually, after failing to stop his death, Im Sol chooses a different path: she rewrites the past to avoid ever meeting Sun-Jae — believing that her presence is what led to his tragedy. But Sun-Jae, even in this new timeline, begins to recall memories from the previous one, leading them both to a bittersweet yet happy ending.
Strengths:
The core romance and emotional beats are genuinely strong. The chemistry between the leads works well, especially with Im Sol's arc from fangirl to someone who deeply cares, not out of obsession, but out of gratitude and respect. Sun-Jae, meanwhile, balances charm with emotional vulnerability — a highlight of the show. The soundtrack is fitting and adds to the emotional tone. The second male lead also stands out more than expected, delivering a solid, grounded performance.
Weaknesses:
Where the show falters is in its final stretch (episodes 10–12 and beyond). Instead of ending at a natural emotional high point, the drama adds an unnecessary murder-crime subplot involving a persistent stalker. This twist, while intended to raise stakes, ends up dragging the story and adding melodrama that didn’t need to be there. The emotional impact of Im Sol wanting to save her bias — not just as a fan, but because he saved her — was strong enough without tacking on a suspense thriller angle.
There’s also a gimmicky feel to how she avoids interacting with Sun-Jae during her second trip to the past. The emotional weight would’ve hit harder if the show had focused more on their connection rather than hiding behind misunderstandings and memory resets.
