She said 'my mom' and not 'your grandmother'. Principal Cao's gaze flickered slightly. From one sentence, he could tell that their relationship was very bad. Ye Jian's relatives didn't treat her like family.
No wonder Old Chen didn't say any good words to these people. She was discriminated against by her relatives at a young age. Fortunately, she met Old Chen. If not, her life would be ruined!
That was the truth. In her past life, Ye Jian was controlled by Sun Dongqing and Ye Ying so she didn't meet Principal Chen. Hence, her life was ruined.
Principal Cao finally knew what was happening. He pretended to be stern and said to Ye Jian, "Ye Jian, hurry up and hold the old lady. Even if she isn't your grandmother, we need to respect our elders."
