ONF
To celebrate White Day, boy group ONF is launching a special social media contest, giving fans a chance to win one-of-a-kind keepsakes.

The K-pop group ONF certainly knows how to melt the hearts of its fans, FUSE. This March 14, 2026, “White Day” the group announced an interactive event titled “Nothing is Sweeter Than ONF.” The concept is simple yet effective: fans are invited to share their “sweetest” and most memorable moments spent with the group. This initiative strengthens the special bond ONF shares with its audience, leaning into nostalgia and emotion to mark this traditional holiday.
The contest will run for a very short 32-hour window, creating a real sense of urgency and excitement among fans. To enter, participants must use a specific set of hashtags and include a symbolic image with their post. The prize is highly coveted: 12 original Polaroids of the group will be given away to randomly selected winners. It’s a rare opportunity to own a unique physical item, a far cry from standard mass-produced merch.
By tapping into themes of closeness and gratitude, ONF is turning a simple promotion into a genuine moment of community. The results will be announced on March 18, and there’s no doubt the group’s social media channels will be flooded with thousands of heartfelt messages in the meantime.
Once again, ONF proves that even at the top of the charts, their dedication to their fans remains the primary engine of their success.
