When Will Ayumu Make His Move? Vol. 5 (manga)
Ayumu is steadfast in his promise to himself that he will not ask out his crush and shogi club president, Urushi, until he beats her in a single game of shogi. However, his resolve will be tested at every turn, as his club senpai grows more and more brazen with her own feelings for him and they traverse the minefields of White Day and several totally-not-romantic dates.
