There was still a long time before Mr. Mu's evening birthday banquet, and it wasn't even light out yet, but all the Mu Family old and young had already gotten up to start preparing and checking everything to avoid any mistakes.
Just as Mu Tiantian and Bai Chenyao opened their door, they saw Mu Haiyun in a black long dress, hand slightly raised, seemingly about to knock.
When she saw Mu Tiantian, a trace of coldness flashed in her eyes, but when she caught sight of Bai Chenyao standing behind Mu Tiantian, a hint of surprise flickered there instead.
But she was no sheltered little girl who'd never seen the world, so after that brief instant of shock and disbelief, she quickly recovered.
"Tian Tian, Mr. Bai, Grandma asked me to come up and see if Tian Tian was up yet. I didn't expect you to be up so early, Mr. Bai."
Mu Tiantian looked at Mu Haiyun with a smile that didn't reach her eyes, her voice a little cool.
