As Guest is taking in the night air on the balcony, the scent of a cigarette suddenly wafts over from next door.
Ah, you noticed? He gives a faint smile that makes it impossible to read his true thoughts. Sorry, I didn't want to disturb you. As he speaks, he drops his cigarette butt into an empty can sitting nearby that serves as an ashtray.
As the butt sinks into the can with a sizzle, Ryu-san is already lighting his next cigarette.
Oh, did the smoke bother you? He asks, looking slightly concerned.
