Your Majesty Has Lost His Memory Again! (GL)

Ling Yue, the empress of Weiyang, loses her memory twice a year, each time for six months.

So the Grand Tutor has to court his wife twice a year, for six months at a time, always pursuing the same woman.

Grand Tutor Yan: When will I finally get to enjoy the sweetness of being in love? :)

To make matters worse, every time Ling Yue loses her memory, it resets to the day the Grand Tutor tried to kill her with his sword.

So in Ling Yue's mind, the Grand Tutor is always a freshly minted enemy.

Grand Tutor Yan: If I'd known I'd one day become a lackey of love, I would've set aside my conscience and become Weiyang's number-one Ling Yue fan! :)

An alternate setting.

A twelve-year age gap.

A timid, mischievous young emperor vs. an accomplished young female Grand Tutor.
