Prince Gumball and Marshall Lee had been "friends" since they were little. Soon after finding out that they were mutual friends with Fionna, they seemed to grow farther apart until they met up in a field. After spending more time with the vampire, he realizes his feelings for him. But he worries if the feeling is mutual. Will Marshall feel the same? Or will he reject Gumball and grow apart from him again. (WARNING: YAIO AND SMUT! DO NOT READ IF UNDER 13 OR MATURE ENOUGH!)
