That was right.
This was Xu Enguang's greatest mystery.
Did Big Brother... really know Big Sister?
If they knew each other...
How had they met?
How incredible...
He had actually happened to run into a friend of Big Sister's by such a coincidence?
So, when he had suddenly "changed personality" and taken the initiative to say so much to him... had he somehow...
Already sensed something?
Xiao Xiao blinked.
"Yes."
"I know her."
Xiao Xiao smiled.
It seemed the boy really was surprised by that.
Seeing Xiao Xiao's smiling face, Xu Enguang came to his senses, too.
That question of his...
Xiao Xiao had already admitted that he was the one who'd asked Big Sister to come back and see him...
If they didn't know each other...
Why would Xiao Xiao ask Big Sister to come back and see him?
And why would Big Sister listen to Xiao Xiao?
They must know each other... and they were good friends, too...
Wasn't he good friends with Big Sister?
Xu Enguang couldn't help getting caught up in that thought again.
Why hadn't Big Sister come back to see him on her own?
Why had someone else needed to persuade her before she came back?
Big Sister...
Didn't think of him as a good friend anymore?
But...
When they'd reunited after being apart for so long...
Big Sister hadn't been... very cold toward him...
He'd even had the vague feeling that they'd gone back to the past.
Big Sister was still Big Sister.
The Big Sister who smiled gently at him.
The Big Sister who patiently listened to everything he said.
But...
No.
Something had changed, after all.
Or perhaps he'd finally noticed something from the past that he'd never seen before...
"Xiao Xiao..."
Xu Enguang pressed his lips
