Tang Ye indeed wanted to keep Ning Yu'er by his side, but he couldn't be so selfish. She still had a father waiting for her, which he could tell from the anxious tone in Ning Tianlang's voice the day before.
As for solitude, Tang Ye had never felt lonely. He had always been alone, eating alone, watching movies alone, doing things others couldn't comprehend. He'd act like a clown in front of his colleagues during the day, and at night he was a brooding creature all by himself. He didn't feel lonely, or perhaps he was just used to it.
"No! I won't go. I'll stay with you, Little Mister... please!"
Tang Ye didn't respond but mercilessly wrote on a piece of paper: Pack your things.
Since Ning Yu'er entered his life, Tang Ye knew that there would inevitably be a day when they would part ways, possibly for the rest of their lives. That's why he initially never told her his full name.
If they were never to meet again, what use would remembering his name serve her?
