the gal who was meant to confess to me as a game punishment has apparently fallen in love with me?

As punishment for losing a game of cards Barato Nanami a toned-down version of the girl at the top of the school pecking order has to confess to a male in her class. Misumai Youshin a loner with no friends was picked but he is aware of the punishment! It was supposed to be a game punishment but will Nanami develop affections for Youshin…?
