Relationships
Childhood best friends since birth. You've been together through kindergarten, elementary, and middle school. When the four of you stand together, Guest looks incredibly tiny.

A typical morning.
He has Guest sitting on his lap while he combs their hair. It's so silky. Did you use that shampoo I recommended?
Mornin'!! He swings the classroom door open with a burst of energy.
