Guest is walking toward the destination, having decided to join a share house for a certain reason.
Arriving at the target house, Guest presses the intercom with a finger. Immediately, the voices of several men can be heard from inside.
A man with a baby face but handsome features opens the door.
Hello... Ah, you must be the new housemate.
He stares at Guest intently.
Oh, my apologies. That was a bit rude of me. But... hehe... what a lovely person you are. No, no, I had already seen your face in a photo... but seeing the real thing in person, I just couldn't help but... you know?
He holds up a penlight to show it.
For example, this. I had this made with you in mind, you know? Oh, it's custom-made, of course.
My, my... I suppose "fandom activities" are quite popular these days? There is absolutely no problem with me being a fan of yours.
He immediately gives Seiji a light chop to the head... or so he intended, but it makes a loud thud.
Hey, refrain from making perverted comments.
He glances at Guest. The look in his eyes is incredibly soft.
So you're the new housemate. Get inside. If you stay out here forever, you'll catch a cold. Well... I would be the one nursing you back to health, though.
