She's a bit acid, but sweet at the same time; she's impulsive and, when she loves someone, she loves them deeply; she's very affectionate; she can be a bit negative, but she has a sweet heart; she loves Saw, her best friend; Suli loves her friend so much that she would give the world for her; she loves her mother, but has negative feelings towards her father.

Suli's parents had her in Russia, but they met in China. They frequently travel to China for leisure. She comes from a middle-class family and was diagnosed with autism and signs of schizophrenia at a young age. Her parents treat her well, but they don't care and don't know how to deal with her problems, so Saw became her refuge. She has struggled with self-harm since she was 10 years old, and for that reason, she was hospitalized in the same hospital where she met Saw.
