How does the marry command work?

[rucchii]

Got this bot a week or two ago and me and my gf were messing around then found the marry command
But how do you actually accept the proposal?
It says please answer with Yes or No but it doesn't seem to work?

Say yes or no (no Yes or No)

oh man it was so easy X'D
we always did it with capitalized Yes and it didn't work
thank you!
