"Support" is basically all of them, so I'll just do the ones I actually ship, since that's what I assume you meant:

Eribo don't go on dates that often, what with Bo still having strong issues with socialising, and they usually keep it simple when they do go out, like a restaurant, or a quiet long walk. The latter is especially nice, since the reason for these dates is usually to take a break from The Incident's craziness (also, usually suggested by Erica).

Lanchi, on the direct other hand, can almost never let a date go quietly. Chi's made sure to bring her girlfriend to every possible outing she can, even the boring ones, and every single one has resulted in a night to remember. This does mean they also don't go out particularly often, Lanc isn't always in the mood for the insanity.

Marion stick to what they do in canon, get some drinks at a café and argue about whatever's on their mind. Orion used to go all-out whenever he took his wife out on a date, not having much else to do with his money, so he appreciates a more low-key experience when he's with Mar.

Smuk rarely takes either of his partners out to dinner, he much prefers to cook it himself, and not wanting him to be left out of the experience, Rose and Bob don't go alone either. At least, not often. All three of them enjoy the simpler Outings, with stargazing being a particular favourite of Rose's (when she feels up for it).

Smukrose is one of my favourites, and I'm probably the only person who cares about it all that much.

Headcanons for my 3 favourite Failboat Miitopia ships. Entirely because two of these have no content on Tumblr and I want to fix that. Will probably make a Volume 2 at some point

Erica/Bo: Noticing how terrible Chi was at reading, Bo started a book club to teach her, and invited Erica along too, for extra support. Erica agreed, genuinely interested in what Bo was doing, but found herself struggling to follow along with Bo’s book selections, while even Chi was managing that much. She still attends the club, though, because it’s Bo.

The time between Bo’s death and the possession of her corpse is almost entirely absent from her memory, and the vague image of the blank void she was essentially trapped in for all those years, barely understanding what was going on, messed with her mind. Now, she imagines Erica every time that void shows itself in her memory banks, and it helps to push it out.

Lanc/Chi: Lanc has received 11 different emergency phone calls from Chi because she drank unstable liquids she created, and even though she knows her girlfriend will somehow be fine, it never fails to make her panic. She wants to complain about this, but has to hold herself back, considering the fact that Chi has received 3 calls of this nature from Lanc.

Even though Lanc removed herself from the kingdom and cut contact with her father, she is still the heir to his throne, and in accordance with this, so is Chi. Everyone is afraid of what that might mean for the Powdered Peaks, but no-one wants to confront it until the day Lanc’s dad drops dead.

Smuk/Rose: The proposal scene in Season 1 was never meant romantically, Smuk just wanted to impress a new friend with the thing she evidently loved most - Expensive shiny things. However, when he actually proposed to Rose, he gave the exact same speech he did back then. Rose laughs about this nowadays, but Smuk always mentions how it certainly worked in the moment.

Oh. Oh gosh. You thought Rea was just taking a bath. And now you get these? You're literally bright red wow.[>Reply] h9ly shit
