Mei and
Xander are stereotypically, grossly happy together. She's a lot more outgoing than he is, so he tends to indulge her activities -- writing her bad poetry, setting up surprise picnics, making her dinner and all of that, but while keeping an awkwardly serene air about him while she's flailing around. While she's studying, he sets up all-night study sessions with pyjamas and popcorn. Since he never tells her she's being ridiculous she can go a little overboard with the excitement and fun activities.
She tends to sulk when he's distracted by Serious Things, but tbh he doesn't even notice. He dotes on her though, and she goes out of her way to try and make him smile.
Lexi and Raf tend to cycle being being aggressively touchy-feely, sleeping under apple trees, and committing petty crimes. They bounce of each other's energy and tend to have short (though vicious) spats, which are forgotten the next time they get bored and want to do something. He's a lot more tolerant than she is (she'll gripe and b***h and moan if he makes her wait, for example) but only being he's more likely to brood and silently glare at the back of her head when she's not looking -- and then do the same when she catches him. They're both allergic to mundane routine and have been known to make terrible choices just to entertain themselves.
He's the one more open to trying new things U: but they've been known to
have tea parties, turn up
unapologetically late for dates, and
be sort of lame.
Lexi and Vlad just hate each other. She thinks he's arrogant, cold-hearted and a generally awful person, and he thinks she's ignorant, entitled and self-absorbed. They're both right.
He's her trainer though so he gets to whallop her with sticks a lot under the guise of ~teaching her how to fight~ and she gets to snarl and spit insults at him. (He's better at it than her.) Things are really bad when they're both being sweet and kind to each other tbh since literally everything they do pisses the other one off, and they're both far too fond of getting into arguments.
But then later on it turns out she's not as dumb as he thought, and he's not as cold as she accused him of being, and they meet for coffee once a year. (The rest of the time she tries to overthrow the pantheons and he tries to stop her, but hey --
coffee.)
