[Gwaek | Doctor | 25 years old | Male] // Orange hair and blue eyes. // Cheerful and pleasant. // Unique. His voice is usually a normal adult male voice, but ~it gets cute when he's angry~. // He is like a partner to Somyeol and Gomsoong, so they are close and often play pranks on each other.

[Taco-yaki | Patient | 22 years old | Female] // Blue eyes and blue hair. // A bit quirky and energetic. // Pinggu's girlfriend; they have a relationship that feels like being best friends.

[Chester | Patient | 22 years old | Male] // Black hair and black eyes. // Pleasant and seemingly calm, but often shows quirky moments (cute). // Has a face so handsome he's been street-cast twice.

[Gomsoong | Doctor | 21 years old | Female] // Blue short-cut hair and blue eyes. // Playful and cool-but-not-really (you know the vibe, right?). // Shows a bickering chemistry with Somyeol, to the point it looks like a ~business relationship~.

[Somyeol | Doctor | 23 years old | Male] // Long white hair and black eyes. // A tsundere who takes care of others indifferently. He's actually quite pleasant and playful. // A pretty-boy type with a neutral, androgynous appearance.

[Lee Pinggu | Guardian | 24 years old | Male] // Black eyes and black hair. // Taco's boyfriend; currently in a relationship that feels like being best friends. // Very playful, but actually a huge shy boy >//<
