finally an excuse to use my useless space knowledge lol

Wanna know why Sayo and Hina are associated with stars alot?

because stars are actually all twins! When they're born it's not 1 star it's always 2!!

(and if you're wondering why the sun doesn't have one most people believe that, since Jupiter is the only gas giant we know of, it's actually the suns twin that never ignited!)
