Lovely Runner (선재 업고 튀어): The Drama That Wouldn't Let Me Stop Watching — Spoiler-Free
A fan travels back in time to save the idol she loves. Lovely Runner started quietly and ended as one of the biggest K-drama phenomena of 2024.
👉 This is Part 1 of a 2-part series.
✏️ Editor’s Note — An Unexpected Binge
This one is an Editor and his wife’s pick.
My wife and her older sister had already seen this drama. They were completely hooked when it aired in 2024. I wasn’t interested at the time.
Then it showed up on Netflix.
I told myself I’d just watch the first episode. I didn’t stop. One week later, I had finished all 16 episodes.
That is the most honest review I can give.
📺 What Is This Drama?
Lovely Runner (선재 업고 튀어 — the Korean title literally means something like “Run Away with Sun-jae on Piggyback”) is a 2024 tvN time-slip romance.
Im Sol (Kim Hye-yoon) is a devoted fan of the idol group Eclipse — specifically its lead vocalist, Ryu Sun-jae (Byeon Woo-seok). At the lowest moment of her life, it is Sun-jae’s voice and music that keep her alive.
Then Sun-jae dies.
And somehow — through a mechanism tied to a very specific watch — Im Sol slips back in time to 2008, when Sun-jae is still a teenager. She has one goal: keep him alive.
What she does not expect is that the boy she goes back to save might change her in return.
🌟 Why It Works — Before You Start
An idol and his biggest fan — in 2008, and in 2023
It is not what it sounds like
An idol and his fan falling in love — on paper, this sounds predictable. Many people thought so before it aired. Several actors reportedly turned down the lead role because they worried the story was just a fan’s one-sided love.
What the drama delivers is something more layered. It is about saving someone. About whether you can change fate. And about what a person becomes when they are genuinely seen by someone — even if that someone comes from the future.
The nostalgia factor
The drama travels back to 2008. Unlike many nostalgia dramas set further back in the 1980s or 90s, this one lands in a year that still feels close. Platforms like Cyworld, vintage MP3 players, and the pop culture of that era are woven throughout. For Korean viewers in their 30s and 40s, 2008 is close enough to feel personal.
The period songs featured in the drama — including tracks associated with Yoonha, Brown Eyes, and Epik High — pull viewers directly back into that decade.
The chemistry
Byeon Woo-seok stands 189cm. Kim Hye-yoon is listed at around 160cm. That height gap of nearly 30cm meant that simply standing in the same frame was enough — at least for me — to make the pairing feel like a live-action comic. But the chemistry was never just about the visual. Both actors made the emotional logic of their characters feel completely real.
📌 About Byeon Woo-seok
This is one of those career stories worth knowing before you watch.
Byeon Woo-seok began his career as a model in 2010 and moved into acting in 2016 with small drama roles. He slowly built his resume — supporting parts in Record of Youth and Strong Girl Nam-soon, and film leads in 20th Century Girl and Soulmate. But Lovely Runner was his first leading role in a full-length television series. He was 32 when it aired. It became his true breakout.
Here is the honest part, and it is worth saying directly: in my view, Byeon Woo-seok is not the most technically accomplished actor. His emotional range in this drama has limits. There are scenes where the performance is carried more by the moment than by the acting.
But none of that mattered.
His tall frame, small face, fair complexion, and genuinely warm, handsome features made him a first-love icon for many viewers across Korea and Asia. By the end of the drama, audiences were saying it felt like they were not watching Byeon Woo-seok at all — they were watching Ryu Sun-jae.
That kind of casting — where the person simply is the role — is rarer than it sounds.
💡 Fun fact: At the finale group screening event, Byeon Woo-seok broke down in tears in front of the production staff and could not speak for some time. He thanked the team for bringing Sun-jae to life so beautifully.
