The sky turned quiet as a gray tone shrouded the whole place. Darkness crept in slowly.

Inside the quiet and comfortable bedroom, Mu Yuchen stirred slightly after a day of sleep. He opened his eyes and put his hand onto his heavy head, glancing around as he sat up. His eyes returned to normal. When he turned around, he saw a huge pair of eyes watching him.
