Both blinks and onces should happy for their fav's achievements rather than downplaying each other. These two groups achieved so many things for a kpop girl groups. Fans should focus on praise the things for what their fav's achieved but instead they only focus on negative things.
It is rare for girl groups to do this well even new groups thriving and giving competition to them but both twice and bp do this in their 7th and 6th year I think fans give importance to group achievements rather than group itself
