But then Sulli uploaded several more photos of herself gazing into the camera with a mischevious look, only dressed in a one-piece slip. This is where netizens started becoming more concerned and angry. They commented, "If I were Choiza, I'd be thinking hard about how to end my relationship with her... She's gotten to the point of scary", "Does she have mental issues? Why does she keep doing this....", "Are you on drugs?", "She's so weird TT", and more.

Are Sulli's Instagram posts making you worry?
