Recently, ALLDAY PROJECT members Youngseo and Woochan have become the center of these rumors due to their great chemistry.
Yongseo and Woochan held a late-night live broadcast, during which the two stars shared pleasant conversations with fans, but discussions about the duo’s relationship quickly began.
During the live broadcast, Woochan joked, “You should go to bed early. If you sleep late, you won’t grow taller.” He added a tip for a restful sleep: “Listen to Vietra’s Strawberries album. You’ll feel very rested before bed.”
Yongseo responded to Woochan’s advice, saying, “I slept late last night and just woke up… but I’m tall enough even without sleeping early ㅠ.”
This simple interaction between Youngsoo and Woochan caught the attention of fans. One netizen shared the couple’s conversations on the Korean forum PAN, commenting, “ALLDAY PROJECT’s Youngsoo Woochan looks like they’re actually dating,” sparking heated discussions on the forum.


Fans also pointed out brief moments, such as Woochan leaning over Youngsoo to adjust the screen during a broadcast, which sparked controversy online.
Many netizens expressed their excitement over the pair’s alleged relationship, while some believe they’re cute together, but their relationship could ruin their careers and harm the rookie group as a whole.
- They fit well together, but if they dated and then broke up, wouldn’t it be a disaster?
- They seem good together, but they’re not dating, so they’re always together, so it’s likely they’re in a relationship or friends.
- Oh, him saying he won’t grow taller makes me so angry.
- Even among male idols, there are crazy people who conjure fantasies. What if it was between a man and a woman? How exciting would it be? ㅋㅋㅋㅋ They’re people who are unable to live normal lives. They think that since they don’t have friends of the opposite sex, just spending a few hours together necessarily means they’re in love.
- They act like they’re a rapper and his girlfriend.
But Youngseo addressed the issue directly on the DayOff fan platform. She responded to a fan who commented on the duo’s strong chemistry, warning against speculation about their relationship. Youngseo also clarified that her relationship with Woochan is purely friendly, saying, “Haha, our playful banter haha. We’re really close, so everything’s fine. You get my point, right? Don’t worry about it at all!”
Meanwhile, ALLDAY PROJECT is the first co-ed K-pop group from Black Label Entertainment and Teddy Productions. They debuted with the music video for the song “Famous” on June 16. It consists of five members: Annie, Billie, Tarzan, Youngseo, and Woochan, while their official debut was on June 23.
The group achieved their first win just 10 days after their debut, winning the M Countdown Cup for “Famous,” sparking anticipation for the group’s future.
