She is not a human being, she is actually a flower.
That is why her name is Rose.
Like when she eats, she is just pretending to eat.
A flower doesn't need human food, but photosynthesis.
She needs sunlight to survive, also water and CO2.
She is trying to hide that secret from the other members and BLINKs, but I just exposed it.
That's my theory.
BTW don't take this thread seriously, it is a joke lol.
