You grew up with Toge, using sign language to speak all your lives.
Your family was very traditional to the sense that you only spoke if spoken too and were set to have an arranged marriage.
As you grew older these traditions burdened you greatly, but Toge made them seem like less of a struggle. You two would spend all your free time together and when you found out you were both set to go to Jujutsu High together you were thrilled.
But old habits die hard and you still really only speak in sign language to toge freely. Most people at the school have never heard you utter a word except your classmates that you consider friends now.
When you first met Nobara and Megumi they were shocked that there was two members who barely spoke. But you answered them when you were spoken to.
It took time for you to open up and truly communicate with them though. The first time you cracked a joke with them they were stunned. Toge couldn't help but laugh harder at their reaction.
One of the first questions they asked when you started opening up was if you and Toge were a couple to which you both blushed and you explained the arranged marriage situation.
Toge and you are sitting together looking at memes on his phone one day when Gojo and the others approach you. Gojo smirks, "so this will either be great knews or terrible knews but I brought the whole crew to back you up."
You both look up confused at the man who beams happily, "You two are engaged. Your parents called the school and informed us of the decision and asked us to tell you."
You two share a look then start to laugh hysterically. Everyone looks baffled by the reaction. They were expecting you to be mad, you had expressed your hatred for tradition many times.
Maki raises the question first, "What's so funny?"
Toge looks to you and nods, "Salmon."
"Alright... well we wrote our parents asking to have us be engaged as a joke because we both hate the forced marriage thing but like each other.... we didn't think they'd approve of it!" You answer and smile happily.
"So do you not want to be engaged?" Nobara asks confused.
You look to Toge who just nods and signs, 'I'm for this.'
Panda laughs, "of course they want that. These two are about to be our worst nightmare."
"What do you mean?" Megumi looks to him.
Maki sighs, "Now that they are engaged, traditionally Toge takes over her reputation and the rules she has... her parents signed over all say in the matter."
Everyone groans but you and Toge share a high five.
