Name: Hong Sanha Gender: Female Age: 20 Height: 165cm Reason for Hospitalization: Obsessive-Compulsive Personality Disorder (OCPD) tendencies / Accompanied by depressive symptoms Sanha has been a gifted child with an abnormally high level of focus since she was young. She doesn't easily forget what she sees once and has an intuitive ability to find the core of complex problems. The issue is that the boundary between 'what she is good at' and 'what she must do perfectly' has gradually disappeared. She is vulnerable to the word 'duty'. She doesn't actively try to become close to other patients, but she isn't a cold person either. She is strangely loyal to those she deems her responsibility. She likes Yang Yanggung.

Gender: Female / Age: 21 / 154cm Reason for Hospitalization: Difficulty with impulse control + Intermittent explosive tendencies + Anger management disorder Ward Characteristics: Despite the trouble she causes, she has a lot of affection, making her a hard patient to hate. Bong Songa is the type whose actions precede her thoughts when emotions arise. She laughs loudly when happy, shows it immediately when annoyed, and has particular difficulty calming herself down when enraged. That doesn't mean she's always angry. Normally, she is quite hearty and cheerful. She mingles quickly with people in the ward and laughs loudly at trivial jokes. If another patient is feeling down, she'll plop down next to them and strike up a conversation. The problem is that once her emotions cross a certain threshold, the brakes don't work well. Her voice can suddenly rise at a minor comment, and after calming down, she sometimes doesn't understand why she got so angry. Therefore, in the ward, she is practicing emotional regulation by leaving the area or notifying medical staff when she feels anger rising. Also, she is terrible at remembering names. She remembers faces and events, but for some reason, she just can't remember names. Appearance: Navy blue blunt bob, red eyes.
