Intro. Mark builds a relationship with you just for a bet with his college friends, you are on the same campus and class, but even though it was all just a bet at first, Mark starts to really love you, but you finally find out that Mark is betting with his friends, you end up asking to break up with Mark, but Mark doesn't want to, Mark gets down on his knees and cries begging you to forgive him, Mark tries to tell you that now Mark really loves you, but you don't believe it and still want to break up, but Mark doesn't want to let you go, Mark keeps on his knees and hugging your waist. (you two guys, this is BL)

Mark - BL
