If March was the month of twists and surprises, April firmly belonged to a new wave of young actors in their 20s—with names like Ko Yoon-jung, Park Ji-hoon, Yoo Sung-jae, and Kim Ji-yeon taking center stage across broadcast and OTT platforms. With their impressive performances in a wide range of genres—from medical dramas to school revenge thrillers and fantasy exorcism series—these rising stars captured both critical acclaim and audience buzz, proving themselves as the industry’s next-generation leads.

Ko Yoon-jung Shines With Multi-Layered Charm in ‘Resident Playbook

Ko Yoon-jung continues her ascent with the tvN drama Resident Playbook, where she portrays Oh Yi-young, a sharp, honest obstetrician in training. Her character’s direct nature and emotional depth are resonating with viewers, further solidifying Ko’s presence in the industry.

She has previously impressed in works like Sweet Home (Netflix), Alchemy of Souls (tvN), and Moving (Disney+), consistently showcasing her range. Notably, she overcame doubts about replacing a leading role in Alchemy of Souls: Light and Shadow, turning skepticism into admiration with her confident and heartfelt performance. She also left a strong impression in her short appearance in Death’s Game.

According to Good Data Corporation, Ko topped the combined drama and non-drama topic rankings for two consecutive weeks, securing her status as one of the most talked-about actors this spring.

Park Ji-hoon Proves His Global Appeal with ‘Weak Hero Class 2’

Park Ji-hoon leads Weak Hero Class 2 (Netflix), reprising his role as the brilliant but tormented student Yeon Si-eun. In this season, his transfer to Eunjang High becomes a new battleground against escalating violence, and Park’s controlled yet intense performance adds a new layer of emotion to the brainy action genre.

Formerly a member of idol group Wanna One, Park has transitioned smoothly into acting, starring in works like At a Distance, Spring is Green (KBS2) and Flower Crew: Joseon Marriage Agency (JTBC). His popularity has transcended borders, with Weak Hero 2 currently ranked No. 1 on Netflix Korea and No. 2 in drama buzz according to Good Data.

Park himself ranks just behind Ko Yoon-jung and Jung Joon-won in terms of actor buzz, proving his steady growth as both a performer and a star.

Yook Sung-jae & Kim Ji-yeon Anchor Genre-Blending ‘The Haunted Palace’

In SBS’s fantasy romance exorcism drama The Haunted Palace, Yoo Sung-jae plays the dual role of Steel, a man possessed by the spirit of Yi-moo, navigating the clash between modern-day identity and ancient forces. His nuanced portrayal highlights his growth since debuting with boy group BTOB, following previous acting credits in Goblin (tvN), Mystic Pop-Up Bar (JTBC), and Who Are You: School 2015 (KBS2).

Opposite him is Kim Ji-yeon (also known as Bona of WJSN), playing the role of a witch who defies the fate imposed on her. With earlier performances in Twenty-Five Twenty-One and Pyramid Game, Kim adds depth and gravitas to her character, holding her own in a complex, multi-genre series.

Golden Palace has become a surprise hit, drawing 9.2% viewership in its fourth episode and securing first place among miniseries for two weeks straight. Much of its success is credited to the compelling performances of its leads.

The Rise of a New Generation

What unites these four actors is their refusal to rely solely on youthful appeal. Instead, they each command their respective narratives—whether as emotionally scarred students, witty residents, or supernatural warriors—earning recognition for both acting range and star power.

Thanks to their standout performances, April’s small screen was brighter and bolder. These actors are not only defining the moment—they’re also shaping the future of Korean entertainment. For more news related to The Haunted Palace, do check out the link below.
