The late singer and actress Sulli is once again at the center of online discourse after her older brother publicly revealed that she once dated Block B’s P.O a detail that had never been made public before. The revelation, made during a personal livestream on March 31, has drawn heavy criticism for being both unrelated and unnecessary, especially as it comes amid more serious accusations involving actor Kim Soo-hyun.

Sulli’s Brother Revelation During the Livestream

During the livestream, Sulli’s brother stated, “Sulli dated Block B’s P.O for about a year.”

He continued, “P.O even came to our house, drank wine, and spent time with us. That was when they were dating.” “She met P.O first, and then later met Choiza.” And he finally stated, “P.O was a good person.”

This marks the first time Sulli’s alleged relationship with P.O has been mentioned publicly.

The comments come just days after Sulli’s family publicly demanded that Kim Soo-hyun and director Lee Sa-rang (Lee Ro-be) provide statements regarding Sulli’s nude filming scene in the 2017 film “Real.” Her brother had already drawn attention for posting accusatory messages about Kim Soo-hyun on his SNS.

Netizens’ Reactions

However, this unexpected disclosure of Sulli’s past love life — particularly involving another public figure — has been met with strong backlash.

Netizens reacted:

• “Why reveal this at all?”
• “Just because they’re family doesn’t mean they can say whatever they want—this is still defamation of the deceased.”
• “Bringing up unrelated people distracts from the core issue.”
• “Even if it’s true, it’s disrespectful to P.O, who is still active in the industry.”

The post discussing the issue on Theqoo also drew widespread attention, with most comments criticizing Sulli’s brother for crossing a line and dragging in unrelated individuals during an already sensitive time.

Comment on theqoo:

1. Why are you doing this..?
2. Why drag P.O into this when he’s done nothing wrong..?
3. What’s wrong with him? Has he lost his mind?
4. No wonder fans said something was off about him…
5. If they dated and broke up without any issues, that’s purely personal, so why expose the names like that…?

While some sympathize with the pain Sulli’s family continues to endure, many agree that exposing her private relationships — especially ones not linked to the controversies being discussed — crosses a line. Critics argue that such disclosures not only harm Sulli’s legacy but also unfairly involve others like P.O, who has no connection to the current debate.

As calls for respectful remembrance grow louder, many hope the focus returns to seeking justice and understanding the truth behind Sulli’s experiences — without dragging unrelated individuals or past memories into the spotlight.

P.O’s Side Responds

Following the media reports on Sulli’s older brother’s remarks, P.O’s agency Artist Company issued an official statement on April 2, saying, “As this involves personal matters, we are unable to confirm whether it is true or not. Since it was so long ago, it’s difficult to ascertain the details.”
