The Straight-A Student System

"Uncle, selling our house for just $2,000?" Luke was shocked by the sale papers. His uncle had disregarded his mother's claim to their house, left by Luke's late grandmother, due to old traditions.
Luke's life had been tough, plagued by a mysterious illness since high school that left him exhausted and hearing strange sounds. This illness ultimately led to his mother's death from overexertion. The house was all he had left.
When conflicts with his uncle and cousin Julius intensified, Luke experienced a "System Integration," activating the "Straight-A Student System" and "Time Recall." Suddenly, he's back in high school with a chance to change his past after a "Time Reversal" is triggered by a soccer ball incident.
Can Luke use this opportunity to rewrite his fate and save his mother?
