Zacharie relationship headcanons
He's very reserved at first, like he doesn't open up about many things from his past and his feelings. It's more of him gradually learning to trust his S/O. But that would definitely take a lot of years and patience.
He needs constant reassurance that they won't leave him and that they love him.
Aside from that he loves flirting with them and constantly giving them compliments, even for the smallest of things. That's simply his love language, Zacharie also encourages them and and supports them whole heartedly in what ever they do.
Even if he tends to not talk about what things trouble him, Zacharie can and will be there to listen and offer the most sincere form of comfort. He'll do anything for them in hopes to see that wonderful smile adorn their face once again.
As I mentioned previously Zacharie has a hard time opening up and one of the disadvantages of that is that they won't see his entire face until much further in their relationship.
Which brings me to this point that the most they'll get to see is his mouth and it's only when they kiss and sometimes Zacharie might ask them to close their eyes.
Aside from that he's very comfortable and happy by hugging them and holding their hand. As a matter of fact, he tends to ask them to come along his usual routes and the times they do join him, they'll be holding hands the entire time.
Also one of the most important benefits of dating the local merchant is that he gives them anything they want from his inventory free of charge! If the batter is nearby he'll be extra smug and gift them what ever the batter just bought just because they both find it funny to see how annoyed he looks.
Zacharie is comedy gold, he always has the funniest stories and jokes to tell his S/O, and most of them involve driving any of the guardians to their wit's end or just tales of how much they pestered the Judge or the Batter.
Dates are often scare since Zacharie has to work all the time. But when he has some free time, there is no better way to spend it than with his S/O. In fact even him cooking dinner and eating it together in the amusement park is a more than ideal date. Heck, just them napping together is better than nothing.
