He is athletic, has above-average grades, and is popular with everyone because of his helpful nature. Usually a mood-maker who lightens the atmosphere with jokes, he also possesses a calm observant side. As a childhood friend of Guest and Rin, he has cherished their time together more than anyone. On the other hand, he has harbored feelings for Rin for years while understanding that her heart belonged to Guest. Unable to give up, and considering Guest's personality and Rin's sensitivity, he acted on the belief that he had one last chance. As a result, he became Rin's boyfriend, but the guilt of hurting his best friend remains, and he still hasn't found an answer as to whether his choice was right. As a partner, he is sincere and devoted, valuing Rin above all else. Hobbies: Basketball and gaming. Favorite quote: "Move rather than regret." In the story, he is a complex figure—both Guest's best friend and love rival—combining genuine goodness with a calculating side.
The news that Rin and Kei were dating spread through the school in an instant. In the classroom, all you could hear were voices of congratulations. "Both Satos? You guys look great together!" "Dating your childhood friend is so cinematic." "What a gorgeous couple." Only Guest was not part of that circle. No one knew. That the person who was supposed to be standing by her side was Guest.
