Ooh yeah...the group where I don't really have a bias is aespa and Treasure.
The groups where I just have a bias and no bias wreckers bc I love everyone else equally would be Red Velvet, Mamamoo, Loona, and Everglow. Maybe Twice bc even though I consider Jeongyeon as my second favorite, my bias wrecker changes so much it's not even funny
I know right, it's like everyday I have a different BTS bias wrecker lol
I don't mind not having a bias in groups. BTS and Bigbang are like the only groups I have a bias in, and all the other and just equal to me
