It starts with the basic two digit number that ends in 0. It always ends up as a multiple of 9. That is because it is the Distributive Property of Multiplication. 9*n= 10n-n.
That is the same exact thing they're using here. If you're number doesn't end in 0, they make you subtract the number.

Itsudatte itsudatte itsudatte
Sugu yoko de waratteita
Nakushitemo torimodosu kimi wo
I will never leave you
