Stolen Future: Swapped for the Impostor

I get sent away to the countryside because my parents fear that I'll use my privileged background to lord over others. In turn, they're taking in Tina from that family to the city for her upbringing and schooling. In the countryside, I get up at 4:00 am daily to feed the pigs, then it's a grueling three-hour trek through the mountains to school. I'm also barely surviving due to constant malnutrition. I reach out to my parents for a mere 300 dollars for tuition, only for them to accuse me of spending recklessly. In the meantime, they're donating an entire building just to secure a spot for Tina at her preferred school. I finally make it into Tina's high school and earn a guaranteed university admission spot, only for my parents to order me to hand it over to her as they unleash their fury on me, yelling, "You're clearly bad to the bone, always trying to take things that belong to Tina." "Tina almost gave up on life because of what you did. You're indebted to her for the rest of your life." They, using their parental rights, forfeit my guaranteed university admission spot to fulfill Tina's wish. They then transfer all company shares and real estate to her for her future security, while the whole family makes arrangements to move abroad together. I take in everything before me, no longer feeling hurt. I calmly pack my belongings and walk away from the place where I don't belong.
