Wedding Xayah and Rakan Skin
As a canon couple, these two should always have skins together, and what better skin for their relationship than a Wedding skin? Especially since Rakan has a specific line that says: "Are you going to marry me today?"
It could be Bride Xayah and Groom Rakan. It doesn't have to be specifically sappy of course.
If there's an enemy Xayah/Rakan and they kill the other Xayah/Rakan (with one of them having the skin), one of the lines they could say is "I want a divorce". Though I'm not sure how that would work and if it would have to be one of them having the skin or both of them. That line is literally why I thought of this skin to begin with
The recall could be them coming together at the wedding altar or something along those lines.
EDIT: Another idea that could be for this skin is that the music for Rakan's ult can change to be the wedding theme or wedding bell chimes or something along those lines (or any one of his skill sound effects).
This is a rough idea so I doubt it will actually become a real skin but I think it's a nice idea. Maybe with more thought it will become more likely to be a skin though.

where they're dance partners or something of the sort. Sure they could do the Tango thing for them as well, but I think there's other dances that they could use in place of the Tango.
*Tango Also makes sense because Rakan
He wanted to ask the bride, but scared that the answer would be "no"
