Marriage hunting but still crushes on younger men?

Rei, a university librarian, is on the hunt for a marriage!
In order to reassure her grandparents who raised her, she is looking for a partner based on “conditions” alone, seeking the title of “married couple”.
Then one day, Rei suddenly receives a public confession from Suwa, a university student.
Suwa, who is a transfer student and has a straightforward personality, is too young and of course out of the question!
But he doesn't give up on her at all...?

A love comedy of a love story about being attacked by a doting boy!
