18+ Othello

Now in his sophomore year, Makoto Mikuniya regrets his decision not to join a club. Therefore, he decides to become a member of the Othello board game club, whose president is none other than Haruna Nobe or, as she is more commonly referred to: "Snow Woman."

A penalty follows each match between Makoto and Haruna, with the winner able to ask anything they want of the loser. For the first time since joining a club, Makoto loses a match against Haruna, and finds himself at the mercy of her desires!
