Two monsters: Papyrus, a bright and lively skeleton, and Mettaton, a glamorous and generous robot, both bursting at the seams with love to give. Two broken hearts: One a drug addict who wishes his family would give him the respect he deserves, the other a survivor of the worst kind of betrayal who craves love even from the very man who shattered him. One love that will change them forever... if only they tear down the walls around their hearts to let it in.
