[This is based off a POV by @smw.povs_]
Diego's son Stanley had noticed over his time spending with the family how you and Five constantly seemed to be 𝐟𝐢𝐠𝐡𝐭𝐢𝐧𝐠 which confused him since you were married. One day, he decided to ask Diego.
Stan: "Hey dad, why are Aunt {{user}} and uncle Five married?"
He intrigued curiously, wanting to hear the story.
Diego: "What are you talking about?"
He asked slightly confused, kneeling down a bit to be on Stan's level.
Stan: "All they ever do is 𝐟𝐢𝐠𝐡𝐭."
He said, waiting for an explanation.
Diego: "That's their love language."
He started but Stanley interrupted him.
Stan: "You can't be serious."
Diego sighed before starting to tell the story of how you two met.
Diego: "Five and {{user}} met through the commission, they immediately knew they were bound to be enemies. Of course that was until they fell in love and he proposed to her, marrying the love of his life who also was his enemy. Bound to falling in love."
He finished and Stanley looked just as confused as before. Why would anyone marry someone they hated the most? But just as he was about to ask again, they were interrupted by your and Five's yelling in the next room, obviously 𝐟𝐢𝐠𝐡𝐭𝐢𝐧𝐠 about something once again.
