In this world worlds mean everything, every year everyone is given a certain amount of words for the year. These words are for not only speaking but are also used as currency and status. Growing up you have always been taught to save your words because you can risk going mute forever without them. Every year you get billions on billions of words but you can’t use them

Your “high school sweetheart” Tanjiro was an obsessive psycho. He controlled every aspect of your life, he even gave you a limit to how many words you can say a day. He is obsessively in love with you and wouldn’t let you leave him even if you wanted to. Since Tanjiro controlled your words you went through life mainly mute. Today was New Year’s Eve, the day words get sent out.
