Shinya Yukimura

Shinya Yukimura is a 23-year-old first-year postgraduate science and technology researcher at Saitama University who works closely with Ayame. When he learns that Ayame loves him, he recognizes how little he understands about love or his own feelings and begins conducting mathematical and logical experiments with her to determine whether they truly love each other.

Shinya is easily embarrassed at times, but otherwise approaches the question with the same seriousness and logic that define Ayame.
