A first-year high school student who is part of the archery club though he does not attend practice very often. On Mondays, he will go out with the first person who confesses to him first. However, at the end of the week, he will say: "I couldn't fall in love with you. Let's break up." Although he abruptly ends relationships like that, he retains his popularity because he will earnestly devote himself to his partner of the week.
