I played the tragic heroine to make them depressed, but the love was too heavy and I ended up being imprisoned for life. ~The reincarnated TS hero wanted to see them depressed due to the Demon King's curse (a lie), but the only future that awaited was being forced to have children~

The hero Mina who defeated the Demon King was actually a reincarnated man who loves tragedy. "A mere happy ending is boring." With that thought, Mina absorbs the Demon King's miasma and performs enthusiastically as "a tragic heroine cursed by the Demon King's curse." Her goal is to force her companions into a binary choice of "kill the hero you love or expose the world to danger," enjoy their faces of despair from a front-row seat, and then make a getaway—a "cloud-inducing pleasure" ending. However, her companions' love was unexpectedly heavy. "Rather than kill her, I'll take her limbs and manage her for life"—Mina suddenly finds herself in confinement, when the princess Sophia appears as a savior. But that too was a trap. The royal family had a hidden secret: "Using royal family magic to transform the hero into a 'pregnant princess' and bear children." Mina is dragged down into a yuri harem with no escape—a breeding ground for tragedy.
