It was exactly 9 months between the start of her 2 month break in December 2022 and the start of her sudden, unannounced 5 month break starting in August 2023.
Also, it wasn't her dancing during the Connect the World concert in July 2023. In over 2 years, Gura has never moved or been able to dance like this before or since. You'll cope and say it was her, but despite her being in over two dozen 3D performances, no one has ever brought back a single timestamp of her dancing as well as she did during this concert with this much energy and movement.
And in June 2023, Kanauru skinwalked her for the MVs he made for Gura's birthday stream.

What kind of health condition is okay in the first 3-4 months, makes things difficult by month 6-7, and then at month 9 culminates with her taking a 5 month break where she was constantly exhausted, wasn't able to sleep, and was out of it every time she appeared anywhere between August and January?
