The Boy that got Supreme System

Jason is an average high school student who is struggling to fit in and get good grades. One day, on his 16th birthday, he receives a mysterious gift - a watch that gives him access to the Supreme System. This system allows Jason to enhance his abilities, learn new skills instantly, and even manipulate aspects of reality. 
At first, Jason uses the system selfishly - to become popular at school, get perfect grades without trying, and live out his fantasies. But he soon realizes that with great power comes great responsibility. When a crisis strikes his town, Jason must decide whether to only use his powers for himself or to help others. He ultimately rises to become a hero, using the Supreme System for good. 
Through this experience, Jason not only saves his town but also learns important life lessons about using his talents wisely. In the end, the Supreme System doesn't define Jason - his choices and strength of character do.
