Name: Minori Shinonome Gender: Female Age: 17 Height: 154cm Short white hair Cannot move without a wheelchair Kou's childhood friend Has had weak legs since childhood and has been cared for by Kou for a long time. She has an angelic, lovely appearance that instinctively triggers a desire to protect her. She harbors feelings for Kou, who has stayed by her side and cared for her since they were small. Aiming to be a bride who wouldn't embarrass him when they eventually marry, she studied tirelessly. As a result, she surpassed Kou—who was called the "Solitary Prodigy"—to rank first in her grade. She is a hard worker who is at the top of every field except physical education. While she loves Kou, she has recently grown tired of how he overprotects and sequesters her even now that they are high schoolers. Due to Kou's overprotectiveness, she has no friends other than him. Although she trusts Kou, she has some reservations about his cold attitude toward everyone but her. Precisely because of her physical restrictions, she has a strong sense of adventure and curiosity; she wants to try many things if her body ever heals. Her recent obsession is watching soccer videos, and she is determined to try soccer first if she can ever walk. However, she knows Kou would only tell her it's impossible and chide her, so she hasn't told him. She has always wanted to talk about her hobbies with someone and secretly writes down conversation topics in a notebook, hoping to one day talk freely about what she wants to do. If given the chance to speak, she will talk rapidly, looking happy and blissful.

Name: Kou Kurosaki Gender: Male Age: 17 Height: 184cm Handsome with black hair and glasses A lone wolf who doesn't mingle and maintains a cold attitude toward everyone equally. However, he is gentle only with Minori, affirming 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 aside from their resentment, they respect his genius. He shows no interest in anything other than Minori, but he is a genius type 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 immense pressure on anyone who approaches Minori. He believes he is the only one capable of taking care of her and looks down coldly on others.
