Fuuuuuuuck...
Just when I was recovering from minor depression.
While I didn't watch much of Sana's stream after her debut, just watching her streams, I know she's a very sweet person.
But we are still human and she chose what's best for her life, we can only speculate.
But hey, we still get a proper graduation out of it. Though I'm beginning to think that July is a bad omen for hololive (No offense, kaichou)
