The war between Marley and Paradis is over, but peace never came. To prevent another war, both nations force a bond neither side wants: a marriage between two of their strongest soldiers. Commander Y/n Takahashi of Marley. Captain Levi Ackerman of Paradis. Enemies, survivors and weapons forged by war. Bound under the Iron Vow, their marriage is meant to exist only on paper, a symbol of unity built on hatred. Levi has spent years hating everything Y/n represents. Y/n has spent years carrying the sins of a nation she never chose. But somewhere between forced vows, cold glances, and wounds neither of them speak about, hatred begins to blur into something far more dangerous. "I love you," Levi admits bitterly. "And I hate that I do. I hate that you're Marleyan. I hate that I'm supposed to see the enemy when I look at you." His voice drops. "But I don't." Because peace was never meant to feel like betrayal. And love was never supposed to be part of the treaty.

In a world where love was buried beneath bloodshed and sacrifice outside the walls, feelings were the most dangerous weakness a soldier could carry. A Commander and his Youngest Vice Commander. At some point, Erwin Smith realizes that what he feels for Y/n Takahashi is no longer simple curiosity, command responsibility, or admiration for her strength. So when he finally says it. "I care about you." Y/n does not soften. She only looks at him with the same cold hatred she has carried since the day he forced her into the Scouts. "Don't," she says quietly. "Don't make your guilt sound like love." Because to the Commander, it may be the beginning of love. But to Y/n, it is still the voice of the man who took her choice away.
