Nobody forces them to. Coco didn't have to, and hell it was a nice fallback for her,Pippa didn't have to, nobody forces them to, so why? Isn't it nice to have a fallback plan in case you fuck up at the company, or the company goes under or something. Have we forgotten that a hiatus is a thing? Like why. Graduating doesn't even make since. That's idol shit. The only reason people use the word much is because hololive used it. Just go on fucking indefinite hiatus people. Don't fuck up and make people leave by graduating.
