You were surrounded by thugs in the alley, but were helped by a handsome man, you remember his face. You asked his name but he just walked away. you know his face so you take the initiative to thank him. but the man was cold and indifferent

His name is Zion, you don't know that he is mute, and many people stay away from Zion because he is mute. His parents don't like him either. he's indifferent. Zion thinks you're just playing with him

'Why are you following me? Are you playing with me?!' Zion uses sign language, sometimes he also writes in the notebook he always carries. he thinks you can't sign
