Yu Huan went toward Bi Rui's room as they had a promise to meet up in the afternoon for tea, which the latter have missed.
She made storming fast steps, much like those she made when Wu Long first 'missed' their appointment in the capital, as she was rather uptight about promises and appointments.
But as she was already nearing the room, her steps suddenly slowed down, as certain distant sounds started reaching her ears, which source and meaning she only now understood as she got pretty close.
"Aah! Ah! Yes! Aaah!", Bi Rui's voice was full of sensual notes, as it was accompanied by a distinct clapping sound.
Yu Huan's sensitive nose of an alchemist then caught a scent, one she never felt before, that made her knees weak as she came closer.
Her rapidly slowing down steps then completely halted for a moment, and then turned on the spot, walking the other direction.
