Naturally, Song Enya would not want to divulge how she had created a false impression of her being his 'official' girlfriend to put his lover down that night!
She took it for granted that, since Mu Yancheng would become her husband sooner or later, she had to eliminate all those messy relationships in his life so as to consolidate her position as his 'rightful wife'. This was because she had no way to retreat from this marriage transaction anymore!
Therefore, she acquiesced to his suspicions and replied matter-of-factly, "You are my fiancé and my future husband, so as your future wife, naturally, I must know about your past clearly, or else if some lowly affairs get exposed when we are ready to tie the knots, it'll be humiliating for me even if you don't feel embarrassed!"
As she finished her words, she stirred her coffee carelessly even though she was feeling rather dismal about almost giving herself away.
She had spoken out of turn in a fit of rage.
