A cozy transbian isekai novel that offers a bit of spice and sweet romance.

Brandon June is a mail carrier who feels unlucky. He likes his job, but he seems to encounter a lot of bad luck (flat tires, lost letters, forgotten bills, etc). One day, while out on his route, Brandon comes across a kid whose toy is stuck in some railroad tracks. Seeing the approaching train, Brandon selflessly throws the kid to safety and takes the blow that would've killed them.

Waking up between worlds, Brandon learns from a Fate Goddess that he'll get another chance at life.

He's reincarnated in a magical world as a Bunny Goddess who delivers luck to those around her. Able to now see strings of good luck and bad luck, it isn't long before she meets a traveling messenger. Drawn to her mission of taking important letters across the land, the newborn goddess climbs into the messenger's wagon and resolves to deliver as much luck as she can along the way.

On their journeys together, the Luck Bunny begins to question things like why being reborn as a goddess felt so right, what it means to rely on other people for once, and how to let oneself fall in love when the right opportunity presents itself.
