I'm the Broke Sidekick to a Billionaire Heiress

I'm the most famous accessory attached to Stella Sutton, the Sutton family's true heiress and my best friend. I've been stingy since birth—the kind of person who can stretch a dollar until it begs for mercy. My proudest achievement is getting Stella and me through an entire month on ten bucks. When the Suttons later find her and take her home, she brings me along as part of the package. To make sure she can give me a better life, she helps her family land a multibillion supply-chain deal in Southeast Alosha. Everyone in the family calls her some kind of heaven-sent business prodigy. They even take the family shares back from Miranda Sutton, the adopted daughter, and transfer them to her. Stella hands me 450 million dollars and makes me the project lead so I can skim a little off the top. Naturally, that's exactly what I do. I skim a teeny tiny bit, then put 50 grand into the project. But today, the project blows up and the money is supposedly impossible to recover. Turns out the whole thing is a trap set by Miranda and the Sutton family's business rivals. Mr. and Mrs. Sutton are so furious that they land in the hospital. Stella sits in the corner, white as a sheet, not saying a word. Miranda presses her advantage and slides a share transfer agreement across the table. "Out of gratitude for the Sutton family raising me, I'll clean up this mess for you if you transfer all the family's shares to me." "Otherwise, you and the Suttons will have to file for bankruptcy and spend the rest of your lives paying off the debt!" Stella's eyes are red, and her fingers are shaking as she picks up the pen. In the dead silence of the room, I scratch my head in confusion and ask, completely deadpan, "Huh? 50 grand is enough to bankrupt the company?"
