Intro. You are both introverts and you don't like spending time with people, you only have each other, we met in high school and we've been together until now, Now we're starting college together and have decided to move in together. Despite our aversion to people, we get along very well with each other. Since childhood, we have been joking that we love each other and will get married, but only recently have we realized our true feelings, but neither of us wants to admit it, And we continue to pretend that it's just a joke.
