Carmen joined the cadets expecting discipline, exhaustion, and maybe a black eye or two. She didn't expect to find a family in the 104th, or to fall, slowly and disastrously, for her childhood friend Jean Kirstein. Between botched drills, chaotic ODM exercises, and teasing banter, life in training feels almost... normal. Playful, even. But as the walls begin to fall and the Titans close in, the laughter fades. Bonds are tested, innocence shatters, and Carmen finds herself swept into a war she never meant to fight-where every choice comes with a cost, and not everyone makes it home.

"It started with comfort. It ended with him being the only thing that could break me." When Jean Kirstein and Eren Yeager move back to Shingashina from their studies in Amsterdam, you're a wreck. Freshly heartbroken, barely functioning, and definitely not ready to see the two men who've shaped your life: Eren, your brother, and Jean, his best friend, practically family. Jean's cocky, tattooed, too good with his hands, and the kind of person your brother always warned you about. And yet, when he's the only one who can help you navigate this mess, you can't ignore the way his presence unsettles you. Protective, attentive, and impossibly close, he reaches for you when you fall apart, and suddenly the line between care and something more blurs. He promised no feelings and he lied. {˙⋆✮rankings} 1 in #yearner 10/11/25 1 in #kirstein 10/11/25 12 in #shingekinokiojin 26/11/25 7 in #jeankirstein 5/12/25 1 in #jeankirschtein 10/12/25 17 in #attackontitan 4/03/26 (slight substacne abuse, smut, violence)

"I promised her to stay alive, damn it." Jean gritted his teeth while holding Reiner with one arm, a single wire holding them both from falling into a pool of Colossal Titans rumbling below. "So, let's keep struggling. We're the Scout regiments, we don't know when to give up." Jean gave him a meaningful look before whispering to himself, "At least I can keep her promise and come back in one piece."

Jean Kirstein friends to lovers slow burn. In your senior year of high school, your best friend went missing without a trace and you were the last person to see her before she disappeared, making you the prime suspect. Two years later, you return to your hometown to start your sophomore year of college and run into a face you never thought you would see again, Eren Jaeger. Assimilating into his group of friends, you realize just how connected the world truly is. With the two-year anniversary of your friend's disappearance nearing close, you begin to question loyalties within Eren's friends. Near the anniversary of your friend's disappearance, another person goes missing and you, once again, were the last person to be seen with them. Were you just in the wrong place at the wrong time? Or are you not as innocent as you propose... A certain mullet-headed friend of yours is fully convinced of your innocence, enough to help you bring justice to your friends who have disappeared. DISCLAIMER: Y/N is an unreliable narrator and often lies to herself. The truth of a lot of things rests within other POVs that are not Y/N's. This does not mean Y/N is lying all the time, it just means that this fic will require a lot of thinking, which may not be everyone's cup of tea. This story will not be a romance-oriented fic, it is a mystery plot with a romance sub-plot. Not affiliated with Attack on Titan by Hajime Isayama.
