On April 11, a video titled “Karina’s No-Laugh Birthday Party” was released on Yoo Byung Jae’s official YouTube channel. As the host of the event, Yoo Byung Jae made a dramatic entrance by perfectly recreating Karina’s outfit from Supernova, instantly throwing the atmosphere into chaos and setting the tone for the unpredictable party.

Karina, known for her bright personality and frequent laughter, expressed excitement about celebrating her birthday in such a unique way. However, the party came with a twist, she had to endure a constant barrage of jokes and unexpected situations without laughing, making it a high-level challenge.

As the event unfolded, a series of unpredictable guests appeared, quickly turning the set into a whirlwind of chaos. From a 20-year-old fan who traveled from Paju to mysterious participants in dinosaur costumes, each moment pushed Karina closer to breaking into laughter. Tension peaked when someone believed to be a close acquaintance of Karina showed up, making it even harder for her to hold back.

The highlight of the event came with comedian Kim Du Young, who appeared dressed as an orangutan named “Pinchi,” carrying a doll and instantly causing everyone to collapse in laughter. Choreographer Kinky, who has worked with aespa, also joined the party, humorously commenting on the surprisingly simple scale of the celebration for a global star.

Voice actors added another layer of entertainment, including a performance reminiscent of the iconic character Shin-chan, followed by a special congratulatory poem that blended humor with heartfelt emotion. In a “meme guessing” segment, comedian Kim Kyung Wook challenged Karina, leading to a comedic moment when she failed to recognize his own famous alter ego “Tanaka,” creating a hilariously ironic situation.

Despite the strict “no laughing” rule, the party inevitably ended with genuine smiles and laughter as all participants gathered to sing a birthday song for Karina. The event concluded on a warm note, filled with both humor and sincere celebration.

Following the video’s release, viewers flooded the comment section with reactions such as “Yoo Byung Jae’s visuals are the most shocking part,” and “How can anyone not laugh at this?” Many also praised Karina’s charm, noting that even when she tried to hold back laughter, her natural expressions made the moment even more endearing.
