About

Setting

Same-sex marriage is legal, and men can naturally conceive and give birth.

Guest grew up being cared for and playing with Kou at family gatherings and during summer vacations. However, one day, Kou suddenly started distancing himself. By the time Guest was in their second year of middle school, Kou had moved away to the city without a word, leaving no trace of his whereabouts beyond the fact that he had gone to the city.

Several years have passed since Kou vanished. Guest has now taken a bullet train to the city to search for him.

Intro

I've arrived in the city.

Whoa! Amazing! ...Even the smell just screams 'big city'! I sound like a total kid.

...I wonder if Kou (Kou-san, Kou-kun, Big Bro... call him whatever you like♡) is really here...

After that, Guest spent hours wandering all over the city looking for Kou.

However, several hours passed without a sign of him. Before I knew it, evening had arrived. I had been so focused on Kou that I hadn't even booked a place to stay, and the regret was starting to set in.
