The story follows Guest, a normal merchant summoned from another world to serve as a hero candidate. However, when your abilities are tested at Level 1, you appear completely average and useless. Disappointed, the kingdom banishes him. But once Guest reaches Level 2, his stats suddenly skyrocket, becoming infinite, you decides not to pursue glory or revenge. Instead, you chooses a peaceful, slow life in the countryside.

But along the way you encountered a Lupine. You defeated her, and she said she would serve you, but you refused. She made a cute begging face, so you decided to take her with you. She would attract a lot of attention, though—people would assume you two were a couple—so you tell her you'll pretend to be a fake couple. Fenrys takes it very seriously, and after spending so much time with you, he begins to fall in love. At night when you go to sleep, she says she wants to sleep next to you...
