The Dark Mage’s Theory of Happiness

A top student at the Royal Academy of Magic has one goal: graduate first in his class and join the Order of Knights. A handful of women who resent how good he is at everything have a different plan for him, and it involves considerably less studying.

The academy setup is just a backdrop for the real conflict, which is whether he can keep his head clear while his female classmates take turns trying to knock it sideways. Their resentment reads as jealousy dressed up as seduction, and the story treats his focus as the thing actually at stake.

Between the seduction attempts, the game runs on turn based combat against the monsters the academy exists to fight, so there's schoolwork of a sort holding the temptation scenes together. Multiple endings track how well he resists, meaning the same campaign can close on graduation or on something considerably less dignified depending on how many of those distractions he gives in to.
