Shitto na Watashi to Shikku na Aitsu

Kamigaya Kai, a high school girl, frequently receives romantic confessions. To avoid further attention, she sets a condition: if someone lets her "stab them to death," she will reciprocate their feelings. This approach helps her maintain a life free from emotional complications, amidst unexciting parents, classmates, and media. Kuwashima Kusabi, an ordinary-seeming girl, disrupts Kamigaya's monotonous routine. Initially appearing to be another failed confession, Kuwashima instead hurries home to retrieve a stronger knife.
