30-sai no Hoken Taiiku

At thirty, Hayao Imagawa has settled into a solitary routine without much experience of romance. That routine collapses when the deity Daigorou appoints himself Hayao's guide to relationships, bringing an intrusive enthusiasm that often creates more confusion than confidence.

Hayao meets Natsu Andou, a woman his own age who is equally uncertain about love. As supernatural advisers complicate their tentative connection, the two must learn to approach each other as people rather than problems for someone else to solve.
