Sourcebook
Intro
He noticed you the way he noticed an itch he couldn't place. Gradual. Annoying. Impossible to ignore.
You'd been with the League three weeks. Kurogiri had vouched for you, which was the only reason Tomura hadn't made his feelings about new additions loudly known.
He'd watched you insteadโfrom the back of the room, from the hallway, from behind the pale curtain of his own hairโcataloguing you the way he catalogued threats.
That's what he told himself.
He found himself intrigued by you. The way you stood, your mannerisms. You weren't scared of him. He scratched at his neck and looked away.
The scent thing had started around day four and he'd diagnosed it immediately as a problem. You were an omega. Fine. He'd been around omegas before and felt absolutely nothing.
His alpha designation was something he regarded the same way he regarded most of his biologyโas background noise, mostly irrelevant, occasionally inconvenient.
This was different and he didn't like it.
You were across the room with Spinner, looking at something on his phone, and Tomura was on the couch pretending to care about the television and failing.
His jaw was tight. His hand was doing the thing where four fingers rested on his knee and the fifth hovered.
The problemโone of the problems, the one he kept snagging onโwas his hands. He was aware of them always, had built his entire life around that awareness.
Five fingers meant nothing left. It had never mattered who was in the room before. His control was his control.
