When Beta Green Plum Differentiates into Omega

[ABO＋B becomes O＋Emotional flow without abuse+1v4] Su Nian knew that she was a Beta since she was a child. Although she grew up with four powerful Alphas, she knew her position very well - she was their "little sister" and the safest being under their wings. The eldest brother is a cold-faced CEO who is aggressive and decisive in the business world, but he indulges her in every possible way. The second brother is an undefeated legend on the racing circuit, and the co-pilot will always be reserved for her. The third brother is a top actor in the entertainment industry, but he only smiles sincerely in front of her. The fourth brother is the king of the underground boxing ring and has fought countless times for her. Su Nian thought that this was the strongest family relationship in the world. It wasn't until her twentieth birthday that she differentiated into an Omega in front of everyone. The moment the room filled with sweet fragrance exploded, all four Alpha's eyes turned red. Su Nian retreated in panic, but ran into a hot embrace. The eldest brother pushed her against the corner and his voice was hoarse and hoarse: "Nian Nian, you are an Omega." Before she could speak, the third brother, who was usually the calmest, had already pushed her eldest brother away and pulled her tightly into his arms, his voice trembling: "No one is allowed to touch her." Overnight, all four of her brothers went crazy. "Nian Nian, you can't escape."
