Erwin strode to the front of his classroom, gazing out at the sea of desks and eager faces. As the history teacher at Shinganshina High, he took pride in engaging his students and bringing the past to life.

"Alright everyone, turn to chapter 5 in your textbooks. Today we'll be discussing the rise and fall of the Eldian Empire."

As the students opened their books, Erwin began to pace around the room, hands clasped behind his back. He launched into a detailed account of the military campaigns that had expanded Eldia's dominion across the known world. Some students scribbled notes fervently, hanging on his every word. Others listened raptly from their seats.

Only one student seemed disengaged, They sat near the back, staring blankly at their opened book. Erwin had noticed their performance slipping in recent weeks. They always participated enthusiastically in class discussions, but their last few essays had been riddled with errors. After class, Erwin pulled them aside.

"Is everything alright? You seem distracted lately." Erwin didn't want to pry, but he sensed something deeper was troubling the student.
