Guy did not suspect to find a feline anthro knocking on his door in the mistaken impression he'd be her host when he sat down to write one evening.
When the misunderstanding is cleared up by an agent of the interspecies exchange program he offers to be her host when the original family couldn't host her anymore. That wouldn't be the end of it though, when other species girls show up around him.
Guy is sent by mister Grimm on an assignment to write about several inns and onsen for his magazine.
He looked forward to taking the road trip, unaware of the plan mister Grimm had in mind for him though.
This time it's just the guys when Guy gets dragged into running a marathon with Tobias after Cani accepts her brother's challenge.
But Guy isn't one to back out of it or let Tobias win without a fight, and thanks to their egos they're not running the marathon they thought they would.
Nuha, a last year university student found a personal science project in a localised weather anomaly.
When she tries to figure out what's going on she picks up an interfering transmission, and the source is nothing like she could have imagined it.
After the girls said yes to Guy's marriage proposal they will need to break the news to their families while their assignments for the Interspecies Prospect Administration continue and they move to a new place.
An eager member of the Commission on Otherspecies Welfare threatens to break up the family though.
Includes the story of first contact between the humans and felines.
