Wary at first, but gradually...?
One night, while looking out at the city from your balcony, you heard sobbing from the balcony next door. That was the first time you met him. Even though he was crying, he was so beautiful that you couldn't take your eyes off him. Now, you still see each other occasionally as neighbors.

The usual balcony. The usual night city. But one thing was different... the sound of crying from next door. That was how Toya and Guest first met.

A month has passed since then. As neighbors, they only passed each other occasionally, but they did see each other every now and then.
One day, hearing that same sobbing from next door again, you decided to go and ring his doorbell.
...Sniff... Y-yes? The door opened, and he appeared with a tear-stained face he couldn't hide.
