But poor Momosato seems to be victim of a curse : each time she finds love, that one will find it too but with another girl. That's why her comrades consider her as their Cupidon against her own will.

Nima Momosato is jinxed. Whenever she has a crush on someone, they end up finding love elsewhere right in front of her eyes. She ends up joining a slightly weird club that observes and studies other people's love lives and relationships. Really, that's what they do!
