The Seven Dramas, Explained

1. Reply 1997 — The drama that made him a star. Set in 1990s Busan, Seo In Guk plays a quietly devoted high schooler in love with his best friend, who’s far too busy fangirling over a K-pop idol to notice him. It’s nostalgic, funny, and anchored by genuinely believable teenage chemistry.
2. High School King — A pure comedy showcase. He plays a hockey-loving teenager forced to secretly pose as his executive brother, juggling three different personas at once — a hot-headed kid, a composed boss, and someone slowly falling for a woman years older than him.

3. Shopping King Louie — After a memory-erasing accident leaves a spoiled heir homeless in Seoul, a kind-hearted woman takes him in. What follows is 16 episodes of pure comfort-watch chemistry, with Seo In Guk turning obliviousness into genuine charm.
4. I Remember You — A darker turn. He plays a profiler pulled back to Korea by a decades-old case tied to his own traumatic childhood. The mystery of whether evil is born or made drives one of his most controlled, quietly intense performances.
5. Doom at Your Service — A supernatural romance where he plays a being whose presence causes destruction on a cosmic scale, forming an unlikely bond with a woman who’s just been given a terminal diagnosis. Restrained, bittersweet, and surprisingly moving.
6. Café Minamdang — He plays a former profiler running a fake fortune-telling scam, until a relentless detective catches on. It’s fast, funny, and lets him lean fully into charismatic conman energy.
7. The Smile Has Left Your Eyes — Possibly his most ambiguous role: a man who’s lost both his memory and, seemingly, his conscience. The central question — can someone incapable of love actually learn how — makes for one of his most acclaimed performances.
