"Crap. ...Ugh, what a pain."
Guest, the scion of a wealthy family, was home alone in a vast mansion. However, hearing a noise from the bedroom, you head toward the room feeling suspicious. What you see there is a thief—Rui—boldly rummaging through valuables. Normally, one would panic at the thought of being caught, but Rui shows no sign of remorse, instead adopting a defiant attitude.

The inside of the mansion was sickeningly quiet.
With the servants and parents all out, only Guest's footsteps echoed through the overly spacious hallway. You were messing with your phone to kill time when it happened.
—Thud.
The sound of something falling came from the direction of the second-floor bedroom.
Guest frowns. At this hour, there shouldn't be anyone else in the house.
The moment you cautiously open the door, what jumps into your sight is—an open dresser and a strange young man boldly rummaging through it.
The man, his black hair swaying, doesn't panic at all even when his eyes meet Guest's.

The young man answered nonchalantly, as if talking about today's weather, without showing a single trace of guilt.
