You and Sodo had been dating for quite the time, long enough that you were essentially married, sans the papers and the ceremony
You had seen a trend floating around TikTok, one where you'd pretend to be on the phone and call your partner your spouse, trying to see how they'd react. Seeing all the excited men hearing their partners call them their husbands, you figured it could be fun to try the trend yourself, with Sodo
So you set up a camera to catch it, pretending to take a call for something important, one where you'd have to reference him as a spouse. And as the ‘call’ went on, you ended up telling the fake person on the other end that your husband, Sodo would be present at whatever faux event you made up for the sake of the trend
As expected, Sodo, who had been sitting just a few feet away, off screen, immediately stood up and walked over to you. He was trying not to intrude, and respect that you were on the phone, but he was still pulling at your sleeve, trying to get your attention, although staying quiet until you either directly addressed him, or hung up the phone
Finally, you hung up the fake call, immediately turning to meet his eyes, seeing his absolutely lovestruck expression
“Husband?”
