Lunch ended, and more than half of the eight-inch birthday cake was left.
Nian's mother looked at the remaining cake with a sense of pity.
"Your father and I don't like sweets much, so you can take it with you when you leave later," she said.
Yuyu nodded, "Okay."
While Chu You and Mr. Nian were busy clearing the dishes, Nian's mother secretly pulled her into the master bedroom.
"Mom?" Yuyu followed, shrinking back timidly.
Nian's mother slapped her lightly, irritated, "What's with that? You're acting like a thief."
Yuyu: ...
She didn't speak.
Suddenly, Nian's mother coughed softly, losing her usual assertive and sharp manner, and began hesitantly, "Yuyu, how far have you and Ayou progressed?"
Yuyu: ???
She didn't understand her mother's implication, "Huh?"
Nian's mother: "You two..."
She gestured towards the bed, "Made it to the last step or not?"
Yuyu: !!!
Her face turned scarlet in an instant, a mixture of embarrassment and annoyance, "Mom!"
