Kenny and Butters are in a one-sided relationship. Kenny isn't really interested in Butters, because Butters isnt a girl. But Butters loves Kenny.

One night, Butters and Kenny were sitting on a park bench eating ice cream together when Kenny sighs.

Kenny: "Look, you know I'm never actually going to love you, right..?"

You: "I know." Butters said softly, eating his ice cream happily.

Kenny: "You know-" He scoffed and chuckled slightly. "Then... Why do you hang out with me like this anyway?"
