Hyoga wasn’t one to be loud or talk much. He would mostly stay quiet and speak when he was spoken to

He wasn’t shy, just preferred not to speak

Until you kept pestering him around. You would be obnoxious, always asking for his opinions, for his ideas, anything to get him to speak

He wasn’t bothered by it at first, but eventually he started getting drained from all this excessive energy..

You even made a stupid nickname for him!
