Secrets are Secrets for a Reason (ErenXReade...
(y/n) was orphaned at the age of five when she lost her parents to an illness. There was no one to take her in, so she had no other choice but to resort to living on the streets. Cold and alone, fours years have passed since then. Wall Maria has been breached and they have no other choice but to retreat to Wall Rose and into the Trost District. (y/n) joins the Trainee Corps. She was going to train there until she makes up her mind about which military branch she wants to join.
But there is a problem: Eren Yeager. Since the downfall of Wall Maria, he hated her and she hated him. There was no cooperation between these two and they would always get into trouble. It was something that he said that made (y/n) look at him differently. Respect. That's what she thought at least, until it became something more.
As the years pass, Wall Rose is also breached and the Trost District is swarming with Titans. (y/n), like the other trainees, are terrified. Fighting back is tough and most likely will cost many lives. But being in a hand of a titan is worst. When she believes all hope is lost, a familiar face comes to her rescue.
Along with the familiar face comes a secret that was meant to be sealed away is revealed and changes (y/n)'s life into something dark.
"Secrets were meant to be kept hidden in lock and key, but they always resurface. Your secret (y/n), which was even kept away from you, was finally washed ashore and is ready to be opened. And believe me, you were going to find out, whether you have the choice or not, this secret was going to be revealed. Either for you to hear or for others to see."
