"I had my first communication with him when I was six."
"Communication?"
The boy nodded. "It's not the kind of face-to-face communication you imagine. It's a very, very vague communication of consciousness."
"What's it like?"
"Mmm. When I'm asleep, I dream about him and see the world he's in. Actually, the world he's in, is not different from mine. He lives in a house with the exact same furnishings as mine. It's just that, for some reason, it's always dark outside the window and the clouds are dense. I've never seen sunlight in his world." The boy paused, suddenly serious. "That's when I began to suspect I had a second personality. I've read some related information."
Little Yichen frowned. "I've noticed how different you could be. You were always innocent and cute around Mommy, but completely different around me or Daddy, or Li Hanlin. Was that you, too?"
Youyou closed his eyes for a moment, then answered truthfully. "That wasn't me."
