Former S.E.S members reunited and made a surprising revelation regarding a past incident involving former group member Bada.

On March 15th, Bada took a trip down memory lane with Eugene on her YouTube channel. She prepared tteokbokki, a dish they used to enjoy together during their time in the group. The dish evoked nostalgic memories for Bada, who fondly recalled the camaraderie they shared.

Bada said, "I used to think, 'I'll be lonely eating this tteokbokki, and they'll go out after getting asked out by someone' So I was happy when you were home. I wasn't lonely." She added that Eugene was popular with men. 

However, Eugene dropped a bombshell by revealing a surprising incident involving Bada. She said, "Why? So I wouldn't come back home? Right, you used to invite them to our home." Bada dismissed her claim as nonsensical saying, "What do you mean? Do you not remember how many fans we had in front of our home?" But Eugene continued, "She had once invited someone home, and at the time she was using the master bedroom. They didn't come out once they went in. Do you know how surprised I was? I thought my unnie was a baddie."

While Bada tried to stop Eugene from exposing her more saying, "I'm married now," she also partly acknowledged, "Well, but I do remember someone who I couldn't believe was there, was actually there." They then laughed it off together as Eugene said, "I still can't believe it to this date."
