Regardless of whether it's because of the punk, or because of the safety of her baby boy, it all comes down to her personal affairs. Her irresponsible act of taking half a month leave at the busiest time for Ying Jewelry was very irresponsible. It caused great inconvenience for Cheng Ye and Ying Jewelry.
She understood this very well, and she felt very guilty about it.
But, her longing for her son had driven her to madness. Even though she knew full well that what she was doing was unfair to Cheng Ye, she persisted.
Initially, she planned to quit her job. However, after Cheng Ye decided to step back, she felt embarrassed to bring it up again.
As it stands, the notion of her quitting her job is neither practical nor realistic.
Moreover, Cheng Ye had said, when she handed in her holiday application, that there was no need for her to quit her job, if she wished to return to the country to live.
