Here are the rest of my current head canons For Baxter Ward and Coco Last. They do contain SPOILERS.
Coco is also a terrible secret keeper who revealed that Baxter drank underage in their first meeting with Xavier and had to tell Cliff Holden everything every step of the way to stop themselves from spilling the beans because Cliff doesn't know Baxter and therefore couldn't spoil the surprise.
There's no escape for Cliff, if he tries to avoid Coco's gushing, Coco whines to Cove who then asks his father to speak to them.. and we all know he can't say no to Cove
They know exactly what they are doing
Cliff on the other hand, does spend some time questioning his past decisions..
"You didn't even take the twenty! There is no contract!"
"Too late, you are family"
*Cliff making a show of being put out but not being able to hide his (somewhat pained but genuine) smile
He had to put up with three years of gushing that no one else could know about.. you can bet Cliff Holden's wedding speech left an impression.
Baxter definitely falls more in love when hearing how much planning went into things (it's definitely one of those things that still gets him flustered). Coco on the other hand is shameless and very proud of themselves, their husband, and the wedding their Husband planned.
No one knows until Derek's wedding speech that Coco has been doing much the same to Derek. (Because he hasn't met Baxter in person either). Except Derek doesn't even try to escape, he likes to be depended upon. He thinks he can at least do this for his friend even if he can't be there often physically. Despite being in the same city Derek keeps himself busy, Coco's gushing makes a fairly good running soundtrack. It helps that Coco literally sings Baxter's praises fairly often and they have a nice voice. He does not think of that old crush he had at Thirteen, or the voided deal he made back then at all, no sir, not him. He's far too busy. That's true, eventually. He never stopped loving the friendship he has with Coco, and Coco definitely never knew about his crush. His wedding speech is also a doozy, for Baxter at least, Coco is still shameless. Poor Baxter might implode from how red he gets from all the praise.
Given Coco is in the public eye, their relationship becomes public eventually. They make sure Baxter is actually ready, media training, asking him to avoid comment sections, lots of reassurance. They do everything they can to protect Baxter from any downsides of the limelight. They gush so much about him in interviews that there are compilations of "Times interviewers got Coco started on their husband" that are over four hours of just Coco complimenting Baxter while avoiding given personal info. They also get a reputation for being overprotective when an interviewer starts a sentence with "Isn't he too-" and Coco cuts them off to list compliments until the interviewer gives up and just says yes to one in order to keep things going.
Baxter not so secretly loves this side of them, but he can't control his blush whenever Coco gets protective. Whenever it looks like anyone might say the slightest questionable thing about Baxter (friendly teasing aside), Coco interrupts them and lists good things about him until they accept one and leave. (Yes, this does include one unfortunate and unexpected encounter with Baxter's parents at a high end restaurant. The rudeness left them speechless, Baxter pleased and embarrassed, while Coco got a private room with a separate exit for themselves and Baxter).
Coco also knows that Baxter needs to work on his self esteem himself, but they can't help showering him in compliments whenever he looks sad. At first, it doesn't happen in front of company, but one-time at a dinner with family Coco is telling a story that took place after he left their city and Baxter makes a sad face. Coco cuts off their story mid sentence, gently grabs Baxter's cheeks and stares into his eyes while showering him with compliments. They take full advantage of his shock to keep showering him with compliments until he begs them to stop. Baxter is distraught, embarrassed, and unfortunately pleased so he can't really tell them off. Everyone at the table teases an unrepentant Coco while Baxter recovers, and Coco finishes their story.
Later, they talk to Baxter more and decide verbal compliments will be saved (mostly) for when they are alone, but Coco will carry a notebook in their purse exclusively to write down Truths about Baxter Ward. That is the title they give it. It makes Baxter smile and blush a little every time he sees Coco writing in it. Coco for their part, finishes the notebook rather quickly and scrambles over how to give it to him, until they realise they could make it a yearly anniversary tradition to give him one. Baxter reads them just as much for the traces of Coco's wit, the impact they make on the paper with their words and the way they held it, writing in it, as for the compliments. He'd say it's more for the fact he can tell where they were and what they were doing when each compliment was written. Sometimes Coco combined those details with the compliment, but mostly it's because Baxter is observant and notices all the context clues.
Baxter ends up doing most of the cooking, which Coco uses as one of the many things to remind him of what he brings to the relationship. Baxter also remembers the exact day he met Coco Every time. He often plans simple excursions for each one. He finally understands it doesn't always need to be extravagant, sometimes the best moments can be wandering randomly around the city reminiscing. He, of course, continues to be very affectionate in private and initiates many fun dancing rendezvous in his company's ballroom. His personal growth continues and he actually maintains contact with his current friends. With Coco's encouragement he actually manages to swim a little in the ocean and reconnect his middle school friends. He makes Coco feel brave as he triumphs over his past fears in leaps and bounds (barring a few minor setbacks that he is not allowed to ruminate on).
He continues his charity works and grows his business far more than he expected.
He does end up swimming in the ocean with Coco for the first time on the anniversary of their third meeting. Not for longer than a minute, while wearing floaties and a full body wetsuit (that Coco suggested in hopes of helping him feel more comfortable). He manages to swim for longer the second anniversary of their third meeting. And by the third anniversary, he's adamant he doesn't need the (black and white) floaties and manages a whole five minutes with Coco between him and the rest of the ocean. He keeps improving facing his fears more and more, inserting himself in Coco's daily life more confidently every day. In short, Baxter makes Coco blissfully happy, and Coco will keep reminding him of that even after he can recognize it for himself.
