Haachama's first hiatus last year was forced by cover, but not for the reasons you thought.
See haachama's first hiatus came right before her final stream for the schizo arc, in fact simple hours before rather than days...that would've been her final stream on earth as well.
You see, haachama was THIS close to killing herself, and she wa sfoing to do it live on stream but after her parents found the noose in her room, the drugs and bloody blades too they had to stop her, and stop her they did.
They called her manager to tell them and both the tweet and statement were uploaded by her manager because she was en route to a therapist at that point, and now she just gets through the day going heavy on her anti-depressants and the occasional Xanax pill every now and then.
She doesn't actually go to college, she just makes herself believe that she goes to college because she wants to be a regular girl when evidently she isn't, haachama actually spends most of her day sitting in the corner of her room thinking of what ifs and she regrets the day she debuted, and went to Australia.
