So my baby's on the road
Doin' business, sellin' loads
Charmin' everyone there
With the sweetest smile

I have this headcanon for Mai and Katsuya where, after finally getting (it) together, they will lead a long-distance relationship for a while (by mutual agreement and on mutual-ish terms).
I just don't see Mai settling down anytime soon, and neither do I see Katsuya living out of the suitcase for a prolonged period. Since I didn't want either of them having to give up what defines them (Mai - her independence and Kats his support system), this is the compromise i came up with.
Apart from an inevitable snag along the way (having to do with compromise and the ability to commit), this works out pretty well - Katsuya thrives on picking Mai up at the Airport/Railway Station with a stupid flower bouquet (that is then nurtured to death in a team effort within a few days...). He is soon known to all the security personnel and greeted with "Girlfriend's coming home?" (after all, Domino Airport can't be that big). Mai on the other hand, has a concept of "home" for the first time, which initially shocks her (and Katsuya).Katsuya Jounouchi and Mai Kujaku (Yu-Gi-Oh!) are (c) Kazuki Takahashi
PS: Notice the blatantly obvious hints about where this headcanon will be going...
PPS: Yes, in my headcanon, Mai will cut off her hair at some point.
