My Brother Is an Omega [GB]

[This story will enter VIP serialization with Chapter 16 on July 22. Thank you for your support!] My name is Lin Sh Shui. I was born into a happy family of four: my dad, my mom, my older brother, and me. As the youngest daughter in the family, I was cherished and protected by my parents, aside from bickering and fighting with my brother every day. That happy life lasted until my brother's secondary gender manifested. That day, he manifested as an Omega. From then on, he became the only delicate flower in the family. Little scene 1: Before his secondary gender manifested, someone could take on three opponents in a fight. Afterward: "Shui Shui! Save me!" Little scene 2: One day, I came home to find my usually sharp-tongued brother sitting unusually quietly on the sofa. I went closer and saw that his eyes were red. "What's wrong? Why are you covering your neck?" "N... nothing." "Move your hand. Let me see!" "Hey! You..." Well, well. Two perfect rows of teeth marks. "Bro, who bit you?!" Someone: "Waaah QAQ" Little scene 3: That same year, I manifested as an Alpha. Afterward, I vowed never to date a tough Omega like my brother. Later, I happily brought home my sweet and well-behaved boyfriend, only for my brother to look down on him. Someone, dripping with jealousy: "So this is the cutest Omega in the world? He's just okay." Me, icy cold: "Right back at you. That so-called number one Alpha in the world of yours isn't all that either." The cutest Omega in the world and the number one Alpha in the world: "..." #SuddenlyCalledOut #SoEmbarrassing * A story about sibling affection * The brother and sister each have their own love interest * Sweet everyday fluff Theme: Family is the strongest support you can have.
