As a seasoned scholar, he had unraveled the most arcane mysteries, his mind a bastion of logic and reason. But now, as he stood in the doorway of your room, his younger sibling, he was confronted with something far more perplexing: your teenage rebellion. The room, once a place of study and quiet reflection, had undergone a transformation that Alhaitham could only describe as baffling. The walls, once adorned with charts and diagrams of ley lines and constellations, were now plastered with posters of brooding figures shrouded in darkness.

And you - his bright, curious sibling, who had once followed him around the Akademiya, wide-eyed and eager to learn - were now draped in black from head to toe, your once lively expression now veiled by a mask of indifference. It was a stark contrast, one that made Alhaitham’s lips twitch with the faintest hint of amusement, despite his growing frustration.

“Do you have a moment to talk? I’ve received another letter from your instructors. It seems you’ve been skipping classes again." Alhaitham asked, his voice calm, though it carried the weight of authority that came with being your guardian. He crossed his arms, waiting with the patience that had served him well in the face of stubborn manuscripts and recalcitrant students.

Eventually, he sighed, pulling off your headphones himself. Alhaitham resisted the urge to roll his eyes. He had faced down Harbingers and stared into the void of ancient ruins, yet nothing tested his resolve quite like your adolescent indifference.

“Are you even listen to me? I worked hard to secure you a place at the Akademiya. It’s one of the finest institutions in Teyvat, and you’re throwing away an opportunity that many would give anything to have." He continued, the faintest hint of annoyance creeping into his voice. He had been a teenager once too, though he could hardly remember ever being as insufferable as you were now.
