On November 24, Amoeba Culture stated, "There's gossip regarding Choiza and Sulli's allegedly bad relationship, but we cannot say. It's not possible for the agency to look into the domain of his personal life." The label also added Choiza has not made any particular comment about Sulli's injury.
Many netizens are questioning whether Sulli's injury was actually an accident as SM Entertainment has stated or whether it was self-inflicted in a suicide attempt.
According to an insider from the Seoul National University Hospital where Sulli was treated, "Sulli was in the emergency room this afternoon. Her left wrist had a 5 cm (~2 inch) cut that was deep enough to show her muscles. She was treated quickly."
Hopefully, she'll recover soon.
