(Check this out... There’s only one Jondall that you know and Yea I made this.)
Jondall is a very quiet and emotionless person when you first meet him. If you ever see him and that award-winning smile, you’ll probably smile back just because you were caught into his gaze. He’s very charming due to his darkskin persona and 2 dimples. His eyes are brown but they sparkle in the light...
“Hey have you seen Jondall today?”
“No, but that’s surprising because you can spot that smile from a mile away.”
