When I took the final exam for sixth grade in elementary school and I didn't get the ideal score, my parents started asking my part-time brother to give me tutoring. But my brother was always busy with work, so he found a new tutor for me. After school started, my grades improved greatly and I got ideal results in the exam from primary school to junior high school. But he was gone, and we chatted online as usual in the future. The day I came of age I saw him and he became mine.
