Then and Now: K-Drama Heartthrobs Nam Joo-Hyuk and Kim Seon-Ho
Which of these handsome Korean actors made you fall harder?
In one of the biggest debates of 2020, South Korean actors Nam Joo-hyuk and Kim Seon-ho find themselves up against each other on- and off-screen. Throughout Start-Up’s run, fans of the Netflix series couldn’t help choosing their side as early as the first few episodes of the show.
With both vying for the heart of Bae Suzy’s Seo Dal-mi, the headstrong yet determined aspiring CEO, who was deserving of the happy ending with her?

Metro Team Reacts to the Finale of 'Start-Up'
With an intensity reminiscent of the discussion on “The Dress,” one of this year’s most heated discussions is: Who deserved the happy ending with Dal-mi? Was it Nam Joo-hyuk’s Nam Do-san, the awkward yet brilliant AI developer, or Han Ji-pyeong, Kim Seon-ho’s harsh yet soft-hearted investment manager?
It’s been a crazy few weeks between #TeamDoSan and #TeamJiPyeong, but—not-so-spoiler alert!—we’ve always known who’ll get the girl in the end. (Yes, he’s the one on the poster sitting side-by-side with Suzy.) That doesn’t mean we don’t have love for them both, though! Whether you’re a solid Do-san or Ji-pyeong stan (or flip-flopped between the two like me), you’ve got to admit that these two gave you so many feels without fail.


If you’re just as hungover as we are from Sunday’s heart-rending finale, we took a trip down memory lane (a.k.a. stalked) both Nam Joo-hyuk and Kim Seon-ho to fill the Start-Up void we’re feeling. Regardless of the team you’re on, there’s no denying these two made the series such a rollercoaster to watch. Browse our gallery for a look back on the different looks they’ve sported on- and off-camera!

Baby Nam Joo-hyuk
Nam Joo-hyuk was born February 24, 1994 in Busan, South Korea. His name literally translates to “shiny pillar,” a name given to him by his grandfather. He spent most of his growing-up years in Gyeonggi Province where he dreamed of becoming a pro basketball player. How cute was Nam Joo-hyuk as a baby? Aww!

Baby Kim Seon-ho
Kim Seon-ho was born an only child on May 8, 1986 in Seoul, South Korea. When he was in elementary school, he developed a heartbreaking trauma from a harrowing experience involving a robber breaking into their home and harming his mother. Thankfully, acting helped him slowly overcome it. Despite his troubles, here’s Seon-ho being the future heartbreaker he’s going to be!

Modeling Debut
At 19, Nam Joo-hyuk left his hometown to pursue a modeling career in Seoul where he won ‘Top Model’ and debuted on the runway for the SONGZIO S/S ’13 collection. The rolled-out-of-bed look fits the lazy summer vibe completely!

Theater Debut
After graduating from the Seoul Institute of the Arts in 2009, Kim Seon-ho’s first theater play was ‘New Boing Boing’ where he portrayed a playboy named Seong-ki. In 2013, he reprised this same role in the comedic play where he looked every bit a preppy ladies’ man with his layered and styled bowl cut.

First Instagram Post
Nam Joo-hyuk’s first post on Instagram was from November 2013 with musicians Ken!44 and Choix2, presumably a little bit after winning ‘Top Model’ and debuting as a model. The grown-out crew cut is such an off-duty look!

Jung Joon-hyung needs no introduction to rom-com K-Drama fans as the hunky ‘Weightlifting Fairy Kim Bok-joo’ male lead. The floppy parted hair reminds us of our ’90s teen crushes and we’re still here for it four years later.

In yet another play that same year, Seon-ho took the stage as Hyung-seok in ‘Voice of the Millenium’ where he portrayed a young freshman in high school. Aside from the shaggy hair, it’s really the dimple that did it.

The year is now about to end, but not before Nam Joo-hyuk’s Nam Do-san made us root for him with all our hearts in ‘Start-Up.’ While he sported quite the shaggy bowl cut in the first few episodes, Do-san cleaned up well throughout the series—transforming from a boy to a man through the 16 episodes. We love how the character’s shy confidence showed in his transformations, too!

Strong and straightforward, he had a killer wardrobe and even killer looks. He looked clean and sophisticated every single time he was on-screen, fitting of the investment manager he portrayed in the show.
