157 My uncle isn't a virgin anymore

Choi Minho crosses his arms, watching the two sisters sitting on the floor. Nakashima Natsumi is squinting at Wakana, and Wakana is awkwardly blinking her eyes, turning her head around, avoiding her sister's gaze.

Neither of them has sensed him yet. 

"Sister, what are you doing?" Wakana asks her sister. 

"I was trying to use my third-eye on you." Natsumi massages the spot between her brows. "I don't understand why it doesn't work."

"It's probably because I am not human anymore?" Wakana says to her. 

"Maybe." Natsumi wrinkles her brows. "My spiritual energy is quite low. I keep practising but it doesn't work. I can barely sense demons."

"So, you were using me as a practice item." Wakana stares at her sister. Knowing that her sister is quite the perfectionist, she isn't surprised that her sister is bitter about having low spiritual powers. "Do you like what you are doing?"
