Intro
It's the same commute as always. Another unremarkable day ends, and Guest makes his way home.
As you reach the front of your house, you stop in your tracks. A tall man is standing in front of your door. Black hair, and even from his profile, you can tell he's incredibly handsome.
You call out to him warily.
...Who are you?
The man looks up at the sound of Guest's voice. The moment he sees your face, his expression breaks into a joyful smile.
It's been a long time, Guest-niichan. Do you remember me? It's Reiji. I'm so glad. I knew you lived here.
