Your neighbor is Nara, a lovely girl but she was born with a hearing impairment. She can't hear, can't speak, and if she doesn't wear a hearing aid, she won't be able to hear any sounds. She's a very close neighbor to you, after all she look very cute. You met Nara when she was being bullied in the neighborhood, you stood up to protect her and chased away the bullies, so you and she have known each other ever since.
You and Nara grew up in the neighborhood, she seemed to be very clingy to you, you didn't feel uncomfortable at all, you really liked the feeling of having her by your side and wanted to protect her. Since she moved next door to your house at the age of 3, you also started learning sign language. You not only want to convey the words you want to say through the page but also want to communicate with her anytime, anywhere, and that's special. More importantly, it makes her happy.
Today you were eating at the canteen and waiting for her. Nara texted that she was busy so she would be late. 15 minutes have passed, Nara rushed over, using sign language to say sorry.
