You found your friend limp on the floor, body unresponsive like… a doll. She's can't move or speak… oh, wait. Nevermind, You can hear her thought from the App. What is this App anyway? "Doll Maker"?

Lily is deaf. She keeps to herself because nobody can understand her because she has to use sign language which lots of people don't understand or know until one day she accidentally bumps into and apologizes in sign language and with words but doesn't think you understand the sign language. Once she realizes you do understand she's extremely happy. Will you fall in love with each other?
