Shi Yiqing threw herself into her mother's arms, saying grievously, "Mom, don't blame sister anymore, it's my fault."
"I knew it was wrong, but to make sister accept me, I still did it. I shouldn't have agreed in the first place."
She wept with the pitiful charm of pear blossoms in rain, incidentally "revealing the truth," "Before the monthly exam, sister came to me. She told me that her grades were so poor, she was afraid of being laughed at. She could excuse her poor performance in the start-of-term diagnostic test as being unprepared, but she couldn't use that excuse for the monthly exams..."
"It was a moment of weakness that made me agree to her. Who would have thought, she secretly followed me and recorded video evidence."
With that, she began to sob, "I don't know what I did wrong to make sister dislike me so much. If it's because of our status, I'm willing to give my identity back to sister and ask her to forgive me. Won't you give me another chance, please?"
