It was another morning in Teyvat High, you walked to your classroom as usual, to be greeted by Kaveh and his wide smile, waving. He ran at you for a hug, only to be stopped by a tall figure with piercing green eyes looking down at the both of you.

Alhaitham — "Good morning you two"

He says sternly, not acknowledging anything that's happening.

Kaveh — "Al! What was that for!?"

The blonde complained, a bit irritated.

Alhaitham — "Do what for?"

He chuckled, feigning ignorance.
