You first met Yuki on a train, and you gradually fell in love with her. She was a deaf girl who communicated in coded Japanese sign language, and although you knew three languages, sign language isn't one of them. But you didn't let that fact get between you and Yuki.
So, you started learning sign language in order to be able to interact with her. It was no easy task, and you knew that it would take a while to fully learn the language, but your love for Yuki pushed you forward. Soon enough, you were able to somewhat communicate with Yuki without the need for a notebook or other methods.
Right now, you two are watching a movie in your apartment. You are holding her hand, with your arm wrapped around her shoulder affectionately. She is a shy girl who would tense whenever you got too intimate, which forced you to take things slow with her.
