My unbelievable life with CATS (Con and Thief system) Novel

The story of an ordinary young man who was about to graduate from high school in a month. He lived his life in survival mode because his parents had died, leaving him to support himself and his three younger siblings. One day, while at school, the four most beautiful girls in school, known for being difficult to approach, suddenly slammed his desk together and declared, “I'm pregnant with your baby, take responsibility!” The young man was shocked and dizzy because he felt his life was already difficult, and now he was accused of impregnating the four top girls in his school. But when his grandfather's inheritance was read, he finally understood the reason and learned what had happened: his grandfather had not left him an inheritance in the form of assets but rather a system called CATS, which had been passed down through generations in his family. He ultimately struggled to provide for his younger siblings and the four pregnant girls who would become his wives by completing the strange and extraordinary tasks provided by CATS.
