Othello

Makoto Mikuniya, now in his sophomore year, regrets not joining a club during his first year. To make up for it, he decides to join the Othello board game club, whose president is the enigmatic Haruna Nobe, also known as "Snow Woman."

Every match between Makoto and Haruna comes with a penalty: the winner can ask anything of the loser. When Makoto loses to Haruna for the first time, he finds himself at the mercy of her desires, and their relationship begins to shift in unexpected ways.
