He removed his jacket, revealing a white T-shirt underneath. Before he could lift the hem of his shirt to remove it, Nian Xi stopped him. "You don't need to take off your shirt."

Jiang Yuning nodded and lifted the shirt to reveal his back.

Nian Xi was stunned. Why would it be ticklish? Was he easily tickled?

He wrote again, "Tingling."

She was silent.

He flipped his notepad to write, "Electric current, connected, physics reaction."
