"Brother Chen, wake up..." Song Chen was suddenly pushed awake, rubbed his eyes and looked around blankly. The mottled walls, peeling paint on the blackboard, tables and chairs of different heights, the place looks so familiar. He raised his hands to scratch his head out of habit, but was startled by what he saw. A pair of small hands with smooth white skin and slender fingers looked particularly translucent under the dim light. No matter how you look at it, you can't tell that it's the hand of a 28-year-old adult man.
