I am not a deaf nor hard or hearing person so if I do anything offensive please let me know! :) I hope everyone enjoys this!

Y/N fujioka was a twin. She was Haruhis twin but they did not get along together so Haruhi never mentioned her. They used to get along before their mom died, which was when they stopped having a way to communicate. Their mom would sign for y/n and tell Haruhi what she said, their dad would too but now he is always at work so thats why Haruhi and Y/N drifted apart. Will you, y/n finally start to talk to Haruhi? will she fall in love with someone in the process?
