Appearance in the MBC Drama 20th Century Boy and Girl


SF9’s Inseong appeared in the first episode of 20th Century Boy and Girl. Inseong plays the younger counterpart of Gong Ji Won (Kim Ji Suk). In the drama, Inseong takes on a character that shows a sweet, romantic first love and exudes high school nostalgia. It was his first drama, so many are curious about his potential as an actor.

In the drama, Inseong showed great romantic chemistry with Gugudan’s Kang Mina (who plays young Jin Jin). There’s a scene when Ji won and Jin Jin take the same elevator in the mansion, and Ji Won refuses to get off at his floor and insists on walking her to her door. In the end, he shyly kisses her in the elevator.
