My Parents' Adopted Daughter Stole My Gifts

I was separated from my family at a young age and was adopted by my adoptive parents, who treated me very well. The day I turned eighteen and became an adult, my biological parents called me and begged me to meet them. Even though I had not seen them for years, I decided to fly to the city where they lived for a meetup. On the day I arrived, I shopped for gifts to give them as a gesture of goodwill, all while waiting for my biological brother to come and pick me up. When I finally picked up the gifts, a young woman decided to take them for herself. “I want the smoking pipe, the tie, and the necklace she’s holding!” She signaled to the shop assistant with a quirk of her lips, and the latter snatched the gift boxes from me. “Hey, I saw them first!” I was furious, but she looked me up and down with a sneer. “All these items are from the most expensive brands in the store. They cost hundreds of thousands of dollars. Can a penniless loser like you afford them? “I am the daughter of the Ferrero family. My older brother is the heir of the Roccia Gang, the city's most powerful gang. Over here, no one dares fight me over things I’ve set my eyes on.” ‘Ferrero? Isn’t that my biological family?’ I thought. As it turned out, she was the girl my parents had adopted after they lost me. I raised an eyebrow and called my older brother, who was coming to pick me up. “Hey, your adopted sister snatched the gifts I bought for you all. What’re you going to do about it?”
