She walked up behind him and hugged his body from the rear, silent without speaking, just holding onto him like a child clings to a teddy bear.
Gu Kai snapped back to reality, looked down, and gently pried her hands off, turning to ask, "What's wrong?"
"Nothing," she shook her head, stubbornly trying to hug him again, yet still he pushed her away.
"Go to sleep early. Your spirits haven't been very good lately."
Listening to his seemingly caring yet indifferent tone, Su Man looked down, biting her lip hard, and mustered the courage to ask, "Kai, are you still blaming me?"
Gu Kai glanced at her and said nothing.
"I know you blame me. It was my fault; I shouldn't have drugged your tea, but... I really like you... At that time, you liked my sister, so I just kept it to myself and never told you. Now that my sister is gone, can't I replace her and love you?"
