The Forbidden technique

Yuri's eyes scanned the dimly lit tent and came to rest on Divanchi, who sat cross-legged on the ground with her back turned to her. The flickering flames of the candles illuminated the small space and cast shadows on the walls. 

Without a word, Yuri walked towards Divanchi and stopped behind her. Divanchi didn't move or turn around, but she spoke in a calm voice, as if she had been expecting her arrival.

"You already figured it out?" Divanchi asked, her gaze still fixed on the front.

"Of course I did." Yuri responded, looking at Divanchi from behind, "That was the first time you've ever been so worked up… you know something I don't… what is it?" She asked, curiosity hinged on her face.

Yuri's voice carried an impatient tone as she stood behind Divanchi, waiting for a response. Divanchi hesitated for a moment, taking a deep breath before beginning to explain.
