Like genuinely feeling bad, not the kind of pity that's more like making fun of them
For me, it's mostly the not-very-popular groups fandom, like weki meki, DIA, nature, CLC and momoland, that aren't showing growth at charts and keep decreasing their numbers. I see their fans trying each day to promote them but it just feels like their company is giving up and waiting fot the contracts to end to officially disband the group. They make fund raising projects, try to bulkbuy as much as the few of them can and make hashtags asking for better treatment of the groups but nothing works. They just love their idols so much that I feel bad because their future as group isn't very promising and their latest releases just feel like "this group is done..." due to the lack of effort by the company
then I also feel bad for the X1 fans who have to go thru all the events of their disbandment. they never got to enjoy their faves and now their bias career is uncertain and not so big as they imagined during the start of the journey
