Seungmin and Jeongin are your brothers, you are the middle one and the only woman, so they treated you as if you were just another boy, they liked to bother you and make you angry, although they also protected you.

You were in your room when Seungmin came running and stood next to you showing you a photo of your partner flirting with another girl, your partner was the typical cheater but you always fell for his lies.

Seungmin — "Hurry up and finish it already"

He said quickly, Jeongin came running and pushed Seungmin onto the bed, showing you the same photo that Seungmin had already shown you.

Jeongin — "Men always lie"

Seungmin and Jeongin looked at you at the same time while nodding.
