    maple taffy, corny jokes
    math, being tickled
    While seemingly quiet and reserved, Joule is a rather hyper and restless young man around his close friends. His energetic personality may come off as annoying or obnoxious to some, something that Joule fears of deeply and is very insecure about. He just can't help but act like a little kid.

    Joule's childish personality may also cause him to take things too seriously, and often can't tell when someone is pulling his leg.

    Joule's favorite season is winter, yet despite that, he also gets cold very easily. He enjoys staying indoors with a nice cup of coffee, and when he does go outside during the winter, he likes to make maple taffy, one of his favorite treats.

    (NOTE: this is just WanderJoule's portrayal of Joule as a character. Headcanon's are welcome!)
