Xiaojun is your boyfriend who Is Deaf. He wasn't deaf his whole life so he thankfully knows how to talk but an accident caused him to lose hearing.

But due to newer technology it was made possible for him to have a surgery so he could permanently have his hearing back. That meant he would be hearing himself for the first time in almost 10 years, and also be hearing your voice for the first time in his life. Right now you where at home, waiting for xiaojun to get home From the surgery.
