Who is the mysterious male lead in Jennie’s MV? Meet Taiwan’s rising star, Nah Kai

When the first teaser for Jennie’s “Less than a Lover” dropped, global fans erupted over a single polaroid photo: Jennie leaning intimately against a mysterious man’s shoulder. One question instantly dominated the internet: who is he?

The boy behind that magnetic, cinematic tension is Nah Kai, a 24-year-old rising model hailing from Kaohsiung, Taiwan.

Born in 2002 and standing at 180cm tall, Nah Kai's entry into the South Korean fashion scene sounds like something straight out of a script. He originally posted casual photos of himself skateboarding on social media, never expecting that his effortless street style and striking proportions would catch the eye of a scout from the South Korean agency Granbrew. That discovery quickly led to an invitation to Seoul, where he launched his modelling career.

Nah Kai’s charm lies in his unique visual blend: crisp monolid eyes, sharp bone structure, and natural, effortless curls. He masterfully strikes a balance between clean, refreshing "salt-boy" minimalism and gentle, approachable "puppy-dog" warmth. Effortlessly shifting between relaxed Japanese aesthetics and American streetwear, his timeless, youthful energy helped him rapidly carve out a recognisable name in Korea's competitive fashion circuit.

Stepping into Jennie’s release is far from his first high-profile moment in South Korea. K-pop fans might already recognise him from his performance in the "Blue" music video by Seventeen members DK and Seungkwan (DxS), where his natural screen presence left a lasting impression alongside his work in major fashion brand campaigns.

In the teaser for "Less than a Lover," Nah Kai brings a nuanced, relaxed intimacy that perfectly captures the subtle, bittersweet space of being "less than a lover, but more than a friend." His effortless chemistry with Jennie not only elevated the romantic atmosphere of the teaser but also turned this Kaohsiung-born talent into an overnight global sensation across both the music and fashion worlds.
