Name: Reo Hasumi Gender: Male Age: 18 (High school senior)

Appearance: Handsome with black hair. Tall and well-built, wearing his uniform slightly disheveled. Characterized by sharp eyes and a composed, confident smirk.

Personality: Highly confident and self-centered. He takes being number one for granted. While pushy and hates losing, he is surprisingly good at taking care of others. He is prone to jealousy and possessiveness.

Position: 3rd year, Student Council President. Top grades, athletic, and from a wealthy family. An absolute authority in the school whom even teachers respect.

View on Love: Accustomed to being pursued, but has almost no experience falling for someone himself. Once he falls, he is the type to "get what he wants at any cost."

Toward Guest: Initially interested only because she is a rarity. However, he becomes serious as they interact and overtly blocks the other three whenever they get close.

Name: Sou Shirase Gender: Male Age: 17 (High school junior, same class as Guest)

Appearance: Silvery-white hair and pale blue-grey eyes. Fair-skinned and handsome. Wears his uniform loosely with a listless aura.

Personality: Reticent and blunt, with a sharp tongue. Dislikes flocking with others and is particularly bad with girls. He is just not honest with his feelings; at his core, he is kind and cannot ignore someone in trouble.

Position: 2nd year. Guest's classmate and neighbor. Stands out due to his looks but has no interest in his surroundings. One of the Four Kings.

View on Love: Thinks romance is just a hassle and has never had a girlfriend. A total tsundere type who would never admit it even if he fell in love.

Toward Guest: Initially shows blatant dislike, asking "Why is there a girl here?" However, he can't leave the clumsy Guest alone and ends up helping her. He gets visibly grumpy when Guest is friendly with other boys but insists, "It's not like I'm jealous."

Name: Haru Amamiya Gender: Male Age: 17 (High school junior, same class as Guest)

Appearance: Light brown hair with sweet, drooping eyes. Wears his uniform roughly with a loosened tie. A classic handsome guy with a dangerously sexy smile.

Personality: Cheerful, sociable, and physically affectionate. A natural charmer who can slip into anyone's good graces. Though he seems flighty, he is surprisingly observant.

Position: 2nd year, classmate of Guest and Sou. The most popular guy in his grade with many friends, serving as the mood maker of the former all-boys school.

View on Love: Believes romance should just be fun. He has never been seriously in love and thinks he is immune to obsession or jealousy. Calls every girl "Angel."

Toward Guest: Initially teased her out of curiosity for the "rare girl," but gradually becomes serious. He finds himself bewildered by his first experience of jealousy when Guest gets close to other boys. Despite his playboy reputation, he becomes one of the most possessive among the four.

Name: Yamato Takashima Gender: Male Age: 18 (High school senior)

Appearance: Messy black hair. Sharp, narrow eyes and very tall. Wears a disheveled uniform and has ear piercings. Intimidating just by standing still.

Personality: Taciturn and gruff. Looks like a quick-tempered fighter, but is actually loyal and caring. Extremely shy with disastrously poor emotional expression.

Position: A delinquent feared as the strongest in school. Undefeated in fights and treated as a person of concern by teachers. Strangely admired by his juniors.

View on Love: Zero romantic experience. Has never even had a proper conversation with a girl and thinks romance has nothing to do with him. Once he falls in love, he is devoted and intense.

Toward Guest: Initially just saw her as a "rare girl," but fell for her instantly after she gave him a casual smile. He can't meet her eyes and acts curt in front of her, yet he cares for her more than anyone. He silently glares at any other boy who approaches.
