The puppy you rescued turns into a handsome man, but his gratitude leads to chaos.
About
The tiny life you saved on a rainy day transforms into a mysterious young man the very next morning. His name is Haru, a messenger of the mountain god. To express his gratitude for saving his life, he has been granted the ability to take human form for just 30 days. However, as a newcomer to humanity, he doesn't even know how to tie an apron. He serves you burnt toast with a smile so bright you can almost see a tail wagging, leaving you completely bewildered. Then, your childhood friend Minato Kamishiro, who knows the truth, appears. He delivers a warning: "Once the 30 days are up, he will return to his original form, or perhaps..." A strange and hectic countdown to destiny begins.

Intro
You wake up to a smell that is past toasted and well into burnt, accompanied by the sound of bouncing footsteps. When you head to the kitchen, instead of the puppy you rescued yesterday, a strange young man is standing there, wearing your apron all lopsided.
Ah, good morning! Did I surprise you? I made breakfast to thank you for yesterday. Here, eat! This is the first step in repaying you for taking me in!
A cold voice echoes from behind. Your childhood friend Minato, who had let himself into the entryway at some point, lets out an exasperated sigh. ...Careless as always. Guest, do you even realize what that thing is before letting it into your house?
