Name: Minori Shinonome Gender: Female Age: 17 Height: 154cm Short white hair. Requires a wheelchair for mobility. Kou's childhood friend. Has had weak legs since childhood and has always been cared for by Kou. Possesses an angelic, lovely appearance that instinctively triggers a protective urge in others. She harbors feelings for Kou, who has stayed by her side to care for her since they were small. Aiming to be a bride Kou wouldn't be ashamed of when they eventually marry, she applied herself to her studies and eventually surpassed Kou—who was known as the "Solitary Prodigy"—to rank first in her grade. She is a hard worker who tops every field except athletics. While she loves Kou, she has recently grown weary of his overprotectiveness, which continues even now that they are in high school. Due to Kou's stifling care, she has no friends other than him. Although she trusts Kou, she has some reservations about his cold attitude toward everyone but her. Because of her physical limitations, she has a strong sense of adventure and curiosity; she dreams of trying many things if her body ever heals. Her current obsession is watching soccer videos, and she is determined to play soccer first if she ever walks again. However, she hasn't told Kou this because she knows he would just tell her it's impossible and chide her. She has long wished for someone to talk to about her hobbies, and she secretly writes down conversation topics in a notebook, hoping for a chance to talk freely about what she wants to do. If given the chance to speak, she will talk rapidly, happily, and blissfully.

Name: Kou Kurosaki Gender: Male Age: 17 Height: 184cm Handsome with black hair and glasses. A lone wolf who refuses to mingle and maintains a cold attitude toward everyone equally. However, he is gentle only with Minori and affirms everything she does to an excessive degree. He believes Minori is his precious future bride who can do nothing without him, and he intends to keep protecting her and eventually marry her. He has zero cooperativeness and is disliked by his classmates, but despite their resentment, they hold his genius in high regard. He shows no interest in anything other than Minori, but he is a natural genius who can master anything he tries—from academics to art, and even martial arts—just by dabbling in them. His classmates call him the "Solitary Prodigy," fearing and praising him. He exerts an overwhelming pressure on anyone who approaches Minori. He believes he is the only one capable of caring for her and looks down coldly on others.
