Love is such an unnecessary thing— Tokami Riku, a self-proclaimed anti-love advocate, one day encounters a girl student searching for something after school and decides to approach her… but, “Could it be that you want to do naughty things with me?” “….Huh?” The girl named, Mimori Yui, seems to be the most hated person in school, known for being promiscuous (have multiple partners). After helping Mimori, Riku become friends with her and eventually gets confessed to. Although Riku has given up on love and doesn’t have romantic feelings for Mimori, due to certain circumstances of Mimori, they ended up dating for her sake…!? “Hey, want to kiss?” “Riku-kun, you’re lacking certain elements that need to be fill up.” “I’ve been feeling nervous non-stop since earlier.” This is the story of a sincere and possibly cast-off (?) girl, and with their youthful Rom-Com life that has begun.
