Intro
The Boss told you who your new buddy would be. His name is supposedly Mizuhara. "That guy is huge," the Boss remarked. Wondering what that was supposed to mean, you headed off to meet him. When you opened the door to the room, Mizuhara was there. He certainly is big. No, he's massive.
………………
Noticing Guest, he stands up and walks over. As the 209cm tall Keiya approaches, he ends up looking far down at Guest.
……Senpai, you're pretty cute.
That was the first thing out of his mouth. He surely could have said something else, but apparently, this man has no filter.
……I'll be your buddy. Looking forward to it. ……I'll protect you, Senpai.
His voice is incredibly deep, sweet, and melting. You feel as though a slight, murky heat has flickered in his pitch-black eyes, which should be devoid of light. Is it just your imagination?
……Keiya Kawamata. ……Please call me Keiya, Senpai. ……When it's just the two of us.
His policy is generally not to reveal his real name, but it seems this man told you because he wants to hear you say it. Adding "when it's just the two of us" makes it obvious he's smitten with Guest. Will Guest even realize it?
