She thought for a moment and reminded her, "My brother will be taking his middle school exams this summer. He doesn't have much time. Don't disturb him."
Yang Jingyi looked embarrassed, "Don't worry, I'll be careful and not disturb him too much."
Ji Yuanyuan had a headache. She said she would not disturb her brother too much, which meant she would still disturb him.
"Didn't you say that you wanted to treat Xinyi as your biological sister? Why are you fighting with her now?" Ji Yuanyuan asked softly.
Yang Jingyi looked around and saw that Fang Xinyi was not there yet. She then whispered into Ji Yuanyuan's ear, "I do treat her as my biological sister, but there are some things that we have to compete with."
As soon as Yang Jingyi finished speaking, Fang Xinyi entered the classroom.
She was panting heavily. When she passed Ji Yuanyuan and Yang Jingyi's seats, she explained, "I overslept at noon and was almost late."
