Yan Zheke wrapped up her remaining assignments before eight. Stretching her arms, she turned towards Lou Cheng.

"Want to have some cake?" she asked cheerily.

Her sparkling eyes and eager expression made Lou Cheng chuckle.

"Of course!" he answered immediately.

"Okay! I'll make some for you. About time I show off my skills!" declared Yan Zheke, nodding happily. She stood up and secured her hair with a hairclip.

She walked down the stairs and into the kitchen. Then she gathered a few eggs and broke them into two seperate bowls— one for the egg yolks and another for the egg whites.

"Need a hand?" volunteered Lou Cheng who tailed behind her.

"Eh…" Yan Zheke looked up in thought, then passed the large glass bowl with egg whites to Lou Cheng. "Beat the eggs for me."
