"Yes? Yitian here…" he almost whispered, still stunned about what he heard on the phone. He was so scared about what this was about. As if he still was the little one that got beaten up for the first time.

But Chao stood in front of him, and even though he was against Yitian being in touch with her, he took his other hand and squeezed it comfortingly.

"Yes, well, I'm here…" Yitian still had no idea what to say. He was too stunned at her behavior. Chao was reaching out for the phone, but Yitian shook his head.
