In this strange world, there are people with horns and people without. When Tsunoko Yagisawa enters her third year at university, she falls in love with Hanasaka-kun, a student in her class. She loves Hanasaka-kun so much that she can't help but wonder if her feelings for him are genuine. Two children who tend to be delusional can't confess their feelings for a particular reason...?
