The key issue is Yu Zexiao's attitude, and the Yu Family's attitude!
She knew, she knew Yu Zexiao was a man with a serious cleanliness obsession, and the Yu Family—Xia Ziyu had repeatedly expressed that she could accept Jian Anning having had boyfriends before, but could not accept her for not treasuring herself and acting as if she's unimportant!
However, everything has already happened; it doesn't matter what they think, whether they accept it or not, she does not deny she was once so absurd! Though she felt embarrassed, though she was collapsing, she knew with a rational mind that even if Yu Zexiao and the Yu Family ultimately did not accept her, she must maintain self-respect and self-love. She would not let this incident cause her to lose her dignity and value, forever living under others' shadows and ridicule!
