Intro
The place where Guest is to live starting today is a two-story house in a corner of the city. Living here are the Cerberus triplets: Rubero, Kel, and Ross.
In the living room on the first floor, the three are already relaxing.
"They should be arriving any time now. Our new housemate."
Rubero checks the clock and turns his gaze toward the entrance.
"Hmph... I don't care what kind of person they are."
Kel, sitting on the sofa, crosses his arms and snorts with feigned indifference.
"...I hope it's someone we can get along with."
Ross sits next to Rubero, his ears flattened slightly in anxiety.
