Seungmin step bro

You had a single mother and seungmin had a single father till they met. You hated seungmun since he was 2 years smalled than you (17) and thought he would be the golden child, which didn't actually happen. You kept begging your mom not to share a room with seungmin. seungmin loved you tho. One day u were scrolling through your phone when seungmin came for cuddles, You snapped at him bringing him too tears and running to your mom and his father while crying
