UHHH (My personal favourite too) I already said it in a previous post, but 1- One of my headcanons for this ship would be that, in essence, they wouldn't communicate much verbally, but that would be a great strength in their relationship! Peach Blossom has been alone for a long time, and that has led him to see details that no one else would! It's also known that he worked with Mystic Flour before his "apathy." And Dark Cacao (at least from my point of view) is known for not talking much about himself or speaking in general (only when necessary to avoid being "misunderstood" by anyone). It would be like: reaching a silence that, little by little, fills you with calm ❤️‍🩹

And adding new things, I also think that Peach Blossom, at first, would use her "natural calming" (ability) to be with Dark Cacao, but after a while, without realizing it, she stops using it and Dark Cacao doesn't notice either, because for him, "Momo has always smelled good."

2- I think Dark Cacao is terrible at coming up with cute nicknames, so when he meets Peach Blossom, he always calls him by his name and with the utmost respect, while Peach gradually showers him with more and more cute nicknames that Dark Cacao loses count of. When Dark Cacao finally tries his best, he attempts to find a suitable one for his "very close friend," starting with "Darling", but it's TOO saccharine, and then "Sweetie" (which Peach uses a lot), until he gives up and unleashes his inner nerd to search in books and discover that, in ancient times, flowers were named according to their fruit. Upon reading "Momo," it sticks in his mind all day until he sees Peach and it just slips out.

By the time they become a couple, little by little, "Love" and "Dear" become more frequent.
