Who ruled Waterbomb? BIBI vs Sunmi rivalry sparks debate
While BIBI's bold performance at Waterbomb Seoul 2026 drew mixed reviews, Sunmi and Cha Hyun-seung's emotional reunion stole the show.
'Waterbomb Seoul 2026' is making headlines daily due to singer BIBI's provocative performance, while the reunion stage of Sunmi and Cha Hyun-seung, who returned after overcoming leukemia, is being re-highlighted as a touching masterpiece.
The most talked-about performance at this year's Waterbomb was undoubtedly BIBI's stage. Singing hits like 'Bam Yang Gang' and 'Bad X,' BIBI delivered a performance where she stripped off her jumpsuit to reveal a bikini mid-performance. Her intense choreography with male dancers spread rapidly online, sparking heated debates with mixed reviews ranging from praise calling it a 'stage worthy of Waterbomb' to criticism labeling it 'excessive staging.'
However, as time passed, there was a different scene that touched the hearts of fans the most.
It was the moment Sunmi and Cha Hyun-seung shared the stage again.
On the 27th, Sunmi released a short video with Cha Hyun-seung via her SNS. The video captured Sunmi smiling brightly while affectionately stroking Cha's hair, showing their enduring friendship even after finishing their performance.
Previously, Waterbomb's official SNS also released a video of the duo performing with the caption, "This is it! They met again!"
On the 'Waterbomb Seoul 2026' stage held at KINTEX in Goyang, Gyeonggi-do, Sunmi and Cha showcased perfect chemistry by performing her signature song '24 Hours Is Not Enough,' drawing thunderous cheers from the crowd.
The reason their reunion was even more special was that Cha's return itself was a miraculous moment.
Cha suspended all activities last year after being diagnosed with leukemia. Despite passing the final stage of an acting audition, he had to forgo the role to undergo treatment. After long chemotherapy sessions, he personally announced his full recovery last December.
At the time, he received widespread support after confessing, "The battle with illness that felt like it would never end has finally come to a close. While undergoing chemotherapy, I realized that the pain is ultimately a process that keeps me alive. I started to laugh, and as I laughed, my fears gradually disappeared."
The first major stage he stepped on in good health was this Waterbomb.
In 2018, Cha earned the nickname "Sunmi's Dancer" after an intense performance during her '24 Hours Is Not Enough' stage. He subsequently built public recognition through variety shows such as 'Single's Inferno,' 'Be Ambitious,' and 'Physical: 100.'
Watching the two reunite after so long, fans reacted with comments such as, "The combination of Sunmi and Cha Hyun-seung is still the best," "I was moved just seeing him return in good health," "I could feel their sincerity in that short moment of stroking his hair," and "The most memorable stage of this year's Waterbomb.'
While Waterbomb was filled with flashy performances, what left the deepest impression was not the provocative staging, but the reunion of two people standing on the same stage again after enduring such a long journey.
