Highlighting "heartfelt" or "melancholy" moments in romance.

Stories where a character must replace a deceased or departed sibling or friend to satisfy the expectations of others.

This juxtaposition of the "cute" or "gentle" exterior with the rotting psychological horror underneath is a staple of the kigu-naki (cute but scary) or utsu-ge (depressing game) genre. It lures you in with the promise of a touching story, only to leave you questioning the morality of the characters' actions.
