Hanano-san to no Enmusubi wa Muzukashii

Isumi Hanano is an easy-going shrine maiden who is famous for matchmaking, while Masanobu is an awkward head priest whose only friends are a turtle and a sacred tree. Both of them are 30 years old and have no experience in romance. (Of course, they're both virgins!)
These two inexperienced people start out as friends, and through a series of misunderstandings, their love might bud in this warm 4-koma gag manga!
