Win You Over (Stan x Kyle) (South Park)

When Stan has to move from New York back to his childhood town, he is outraged. But when he meets his old super best friend, Kyle, he isn't as bothered. Although, when Kyle finds out his feelings about Stan, he doesn't know what to do, and neither does Stan. - Credit to the artist of the cover
