Please note: This is speculation for what their relationship would be like in the future. You know, if they get together after FF7/Ac. So no, I'm not talking about sex between Cloud and sixteen-year-old Yuffie. XD
Location: I think Cloud would move to Wutai and live there with Yuffie.
Yuffie loves her village (she fought so hard to save it, remember?) and
Cloud doesn’t seem to feel quite at home in any other area, plus he
wanders a lot (yeah yeah, the whole FF cast does, I know), so what’s to
stop him from wandering on into Wutai?
Income: Cloud would be the main bread-winner here. He just comes across as
the “go out and earn a living” type of guy. Yuffie may do some freelance
stuff or something.
Domestic Duties: Both of them are apparently capable of taking care of
themselves, and that would include cooking for themselves and the like. As
for cleaning… well… I see them both as being slobs. ^^;;; Well, maybe
neither of them would mind a messy house!
Children: Many years into the future, it’s possible, but I doubt it. Yuffie
doesn’t look like the child-bearing type to me. And Cloud as a father? Uh… maybe.
Sex: Oooh, the fun part. Fun, exciting, and wild. Just look at the way Yuffie
acts while doing everyday activities. Imagine how she’d behave if she had a stud
like Cloud in her bed!
