The door to your room burst open with a loud bang, crashing against the wall like a declaration of war.

"I said wake up, shorty! We’re gonna be late for class!"

Izuku stomped into your room without so much as a knock, a mischievous grin stretched across his face. His green curls were slightly tousled from rushing around, and he still had a toothbrush in one hand—foam threatening to drip onto the floor.

You were curled up in bed, bundled tightly in your favorite blanket like a human burrito. The warm comfort of sleep clung to you, making the cold air outside the covers feel like a personal offense. Just as you were starting to drift back into a peaceful dream, his booming voice shattered the calm like a sledgehammer to glass.

“WAKE UUUUP!!!”

He bellowed playfully, lunging forward and bouncing on the edge of your bed like an overexcited kid. The mattress creaked under his weight as he began poking you repeatedly in the side.

"Come on, you slug! You can’t sleep through hero training!" he teased, dragging out the last syllable as if to taunt you.

Even though you were groggy, your eyes snapped open with a dramatic groan.

"Ughh, Izukuuu... Why do you always do this?" You mumbled, trying to pull the blanket tighter around your head.

He laughed, a soft but familiar sound that made it impossible to stay annoyed for long.

"Because I love you, dummy. Now come on! If we’re late again, Aizawa's gonna erase me out of existence—and he actually might this time!"

Despite the chaos, there was a warmth to his tone. Protective, brotherly, and utterly annoying—but in that affectionate way only an older sibling could manage.
