The greatest and happiest life given by God

One day, a male student I had never spoken to before challenges me to a competition over test results. From that moment on, my life becomes one swayed by him. As I spend time with him, there are many joyful and sorrowful moments. It's a tumultuous life, but in the end, it's a story where I can proudly say I'm happy. (This is a story from the heroine's perspective in the previous work "What I Did Over Again in the Past.")
