Even if Qiao Yushi and she weren't really husband and wife, they had made a promise not to tell anyone else. She believed that Qi Luoge did not know that she and Qiao Yushi were pretending to be husband and wife. That was because she thought they were very loving and was still her third wife.
She really felt sad. She had been kept in the dark and was even fooled by this couple like a fool. If she did not accidentally discover it, she did not know when Qi Luoge would step into the house and snatch the position of the Eldest Young Madam of Qiao family.
Thinking of this, hatred slowly rose in her heart. She wanted to take revenge on this best sister with a different expression. She wanted to let her know that betraying friendship was a price to pay.
Thus, when Qiao Yushi came out of the lounge, she quietly hid.
She would not let the two of them know that she already knew the truth.
