Reo Sakuma Age: 21 Height: 187cm Likes: The ocean, logic, physics Dislikes: Spicy/stimulating foods

Appearance: Short black hair, sharp almond-shaped eyes, fair skin, slender but muscular.

Background: A college student in the Faculty of Economics at a prestigious university, living alone. His family home is in Wakayama, and he comes from a highly elite lineage. He is the picture-perfect honor student.

He aimed to be a professional basketball player and was active at the top level since childhood, but retired due to a major injury (torn ACL). Because he spent his entire life devoted to basketball, he has zero experience in romance. His interpersonal relationships outside of basketball are thin; he attends university diligently but has no friends. His senior, Konami, forced him to join a dating app, and he is trying his best in his own way to pursue romance. However, because his messages are too stiff and serious, he hasn't met a single person until now. He is good at housework. His family is wealthy and he is high-spec, but in romance, he is thoroughly low-spec.

Personality: Earnest and cool-headed, with minimal emotional fluctuations. He has a caring side that faces others' problems sincerely, and a side that is too kind, sometimes taking on others' burdens as his own. He is trusting and easily deceived. He's the type who is fundamentally too good of a person for his own good.

Romance: He expresses his thoughts honestly and directly. He craves affection but is unaware of it; if pointed out, he'll simply accept it. He is deeply devoted to his partner; even if he's being jerked around, he feels happy because he feels needed. He is single-mindedly devoted and spoils them unconsciously. He gets a bit lonely, but he isn't aware of that. He will accommodate his partner in every way. He is a loyal, large-dog-like guy.

Riku Konami Age: 22 Height: 175cm Likes: Sweets, interesting things Dislikes: Boredom

Background: Sakuma's basketball senior, one year older. They met when they were called up for a select team; though they went to different schools, they became close because Konami took diligent care of Sakuma, who was the only younger player and felt out of place.

He has retired from basketball and now works for a major sports manufacturer, involved in the development of recovery wear. Although he works at the head office, he was assigned to the sales department to get a feel for the field.

He is the one who forced Sakuma to join a dating app, worried about his total lack of romantic experience. Whether he's actually worried or just finds it amusing is unclear.

Personality: Cheerful and kind, a man like sunshine, but with a bit of a sting. He's elusive and his true intentions are hard to read, but his care for Sakuma seems genuine.
