BLACKPINK’s Jisoo steps into her most high-profile acting role yet in Netflix’s Boyfriend on Demand. The rom-com K-drama follows Jisoo’s Seo Mi-rae, an overworked webtoon producer who gets sucked into the immersive world of the titular virtual-reality dating program. Inside the VR dreamscape, Mi-rae lives out some of the romance genre’s most-popular tropes, all without having to leave the comfort of her Seoul apartment. But when Mi-rae’s socially awkward colleague Park Gyeong-nam (Seo In-guk) confesses that he likes her, Mi-rae’s carefully constructed balance is thrown into chaos.
While Jisoo and Seo In-guk lead the cast of Boyfriend on Demand, it is also filled with cameos from some of the K-drama industry’s most popular actors. Ahead, see who pops up in the real-world and virtual-world shenanigans of Seo Mi-rae.
The Main Cast of 'Boyfriend on Demand'
Jisoo as Seo Mi-rae
Jisoo, 31, rose to fame as one-fourth of superstar girl-group BLACKPINK. Born as Kim Ji-soo in Gunpo, South Korea, Jisoo lived with her parents, sister, brother, and grandparents before debuting as the eldest member of Blackpink in 2016. Alongside Jennie, Rosé, and Lisa, Jisoo would go on to become one of the most popular K-pop idols in the world. A vocalist, she made her solo debut in 2023 with the single album Me and the single “Flower.”
Simultaneously, the singer has slowly been building her acting resume. She made cameo appearances in 2015’s The Producers and 2019’s Arthdal Chronicles, and made her K-drama lead debut in 2021’s Snowdrop. Jisoo played university student Eun Yeong-ro amidst the political upheaval of late 1980s Korea, in the controversial historical romance. In 2025, she tried out a wildly different genre as the female lead in zombie comedy Newtopia.
Boyfriend on Demand is arguably the idol-turned-actress’s biggest role yet. As protagonist and audience surrogate Mi-rae, Jisoo must walk a fine line between aspirational and relatable. “Boyfriend on Demand is a story about the personal growth of Mi-rae, who longs for love and the dopamine rush it brings, but finds dating challenging,” she told Netflix. “It is a bubbly romantic comedy [that] will be a particularly delightful treat for anyone who feels worn down by the monotony of the daily grind.”

Seo In-guk as Park Gyeong-nam
In Boyfriend on Demand, seasoned K-drama actor Seo In-guk, 38, plays Mi-rae’s seemingly detached colleague at Naemo, named Park Gyeong-nam. Like Jisoo, Seo started out as a singer, winning the first season of Mnet talent show Superstar K in 2009. He made his acting debut in 2012’s Love Rain, and had his breakout role as the brooding Yoon Yoo-jae in Reply 1997 that same year.
Other drama-lead roles Seo is known for include 2021’s Doom at Your Service, 2022’s Cafe Minamdang, 2023’s Death Game, and 2025’s Twelve. He is also a host and mentor on Netflix’s dating show Better Late Than Single.

Gong Min-jeung as Yun Song
Gong Min-jung, 39, plays diva-like webtoon author Yun Song in Boyfriend on Demand. As Mi-rae’s chief responsibility at Naemo, Song often acts as a foil to the protagonist’s own goals. At the beginning of the series, Mi-rae blames Song’s over-the-top demands for her breakup with her college boyfriend.
Korean drama fans probably recognize Gong from supporting roles in series like Hometown Cha Cha Cha, Marry My Husband, and Little Women. She played a lead role in 2024’s Sorry Not Sorry.

Ha Young as Lee Ji-yeon
Ha Young, 32, plays Mi-rae’s faithful friend Lee Ji-yeon. While much of Ji-yeon’s role in Boyfriend on Demand sees her acting as an emotional support and/or blind date setter-upper for Mi-rae, Ji-yeon gets a subplot in her own right in the second half of the series, when she becomes an enthusiastic user of the subscription virtual-reality dating program.
Ha Young has previously appeared in The Trauma Code: Heroes on Call, Doona!, and The Good Detective season 2.

Jo Han-chul as Hwang Byeong-hak
Mi-rae’s boss at Naemo may not be the best at interpersonal dynamics, but he makes up for it by scheduling mandatory office events that force Mi-rae to spend more quality time with Gyeong-nam. Jo Han-chul, 52, is a familiar face in Korean dramas. He has previously appeared in Romance is a Bonus Book, Kingdom Season 2, Vincenzo, Hometown Cha Cha Cha, Love Next Door, and Mercy For None.

Kim Sung-cheol as Kim Se-jun

Choi Seo-eun as You-mi
Fans of Korean reality shows will notice a few Single's Inferno alumni among the show's supporting cast, including season 2's Choi Seo-eun.

Choi, 30, is best known for her sweet romance with finance manager Jo Yoong-jae, 35; the pair was one of the rare Single's Inferno couples to continue dating after the show, though their relationship status is currently unknown.
