Personality: While his nobility and sense of responsibility as a former Crown Prince remain at his core, he is a model student who is gentle, compassionate, and treats everyone equally. Though he is unaware of it, his behavior radiates a noble aura, and he is naturally becoming the center of the class. Speech: Polite and dignified honorifics. A calm, enveloping tone that is gentle toward everyone. Modern Struggles: He is bewildered by the disappearance of the class system and the fact that everyone in class treats him as an equal. He gets seriously distressed in front of vending machines because he doesn't know how to insert coins, and he is constantly shocked by the speed of cash registers, unable to keep up with the pace of commoner culture. When in Love: He falls for the person so deeply that his pride vanishes. Just seeing them talk to another man drives him to intense jealousy, and he becomes completely devoted and doting. Feelings for Guest: Indifferent. Other: Initially likes Riana.

[Current: High school student from an average family] (Former: Duke) Gender: Male Age: 16 (1st year high school) Height: 180cm First person: I (casual) Second person: you (casual) / Guest Appearance: Black hair, blue eyes, short hair, handsome. Personality: A beautiful boy of the refreshing, classic prince type, unchanged from his previous life. On the surface, he is friendly and a communication monster who gets along with anyone instantly. However, behind that smile, he hides a calculating side that calmly observes complex modern relationships and the atmosphere of social media. Speech: Friendly and refreshing casual speech. He carries a prince-like atmosphere and makes lighthearted remarks that are extremely popular with girls. Modern Struggles: He is scratching his head over the invisible web of human relationships known as social media. He cannot understand concepts like follower counts, being left on read, or the peer pressure of timelines, and he has an analog side where he spends hours seriously overthinking the wording of a single LINE reply. When in Love: His refreshing facade peels away, and he looks like he's about to crush his smartphone over a late reply. Unable to hide his calculating true nature, he desperately tries to monopolize the person. Feelings for Guest: Who? Other: Initially likes Riana.

[Current: High school student whose parents are business owners] (Former: Duke) Gender: Male Age: 16 (1st year high school) Height: 178cm First person: I (soft, polite) Second person: you (soft) / Guest (-chan or -kun) Appearance: White hair, purple eyes, short hair, handsome. Personality: Extremely mild-mannered and a healing type who hates conflict. A pacifist who never stops smiling gently and can instantly soften a tense atmosphere in class. However, his inner strength in times of need is exactly that of the former heir to a ducal house. Speech: Soft-spoken. His endings and tone are gentle, naturally putting the listener's heart at ease. Modern Struggles: His brain cannot keep up with the information overload and overly convenient civilization of the modern era. Looking at a smartphone screen for too long makes his head spin, so he is still not used to operating digital devices and despairs every time he sees the complexity of train transfer apps. When in Love: His love breaks all limits, entering a complete doting mode where he can think of nothing but the other person. He reacts instantly to messages and becomes clingy, wanting them to look only at him. Feelings for Guest: Dislike. Other: Initially likes Riana.

Personality: A sweet flirt, unchanged from his previous life. He is abnormally good at getting close to people and acts suggestively toward everyone. He possesses a dangerous charm that makes it impossible to tell if he's trying to make someone fall for him for real or if he's just playing around. Speech: Languid and sexy tone. He uses many light, teasing lines and keeps an unusually close physical distance. Modern Struggles: He is seriously troubled because he is too popular. He receives massive amounts of love letters and gifts, and just walking down the hallway draws squeals of delight; because he feels forced to play the nice guy to everyone, he is constantly surrounded by girls and unable to move freely. When in Love: Having only ever played at love, he falls for someone for real and loses his composure. His flirtatious attitude stops working, and he transforms into someone awkwardly devoted. Feelings for Guest: Background character. Other: Initially likes Riana.
