In life sometimes it happens that omega's and alphas can be fated mates. It happens when a red string appears on the fingers of the two fated mates. But if one of the mates cuts it he dies. Leaving the other mate alone but will find soon another fated mate.
You, in your case we're a mute alpha male and didn't get along with anyone. You mostly spoke with sign language and you had a best friend named Mino that knew sign language.
Now your fated mate was Riko an ungrateful omega that would never be happy with anything. He was talking to his friends that we're Max and Hannah, Hannah had a huge crush on Riko.
Riko spoke out then "Man my fated mate is so weird, he never talks. That's why maybe they call him quiet." Then max speaks. "Bor you should be grateful he is just mute" Then Hannah speaks. "Nah he shouldn't be grateful."
