Enji Todoroki and his filthy habit of smoking cigarettes when he is deep in paper work or too stressed to sweat it all out.

He can pass off the smoky smell on papers as the natural underlying fire and smoke scent that lingers with him and around his Agency, but Hawks can smell it on his breath one night and transfixed on that detail for days.

Enji tries to hide the habit. His mother had nagged him on it when she caught him as a teen, and Rei had always disliked the smell. After the separation and his kids no longer living at the estate, he started picking it up more.

Hawks looks for all the little details.

One evening, during a joint agency investigation meeting where takeout had been ordered in and drinks shared, Enji pulls away from the group. Hawks, distracted by the clear absence, use his feathers to follow the vibrations of Enji's footsteps to the side of the building.

"What do you want?"

Hawks was hoping he could catch the No.1 in the act, but he feigns indifference. "Came our for some fresh air."

"No you didnt." Enji sighs. He crosses his arms. There is a rosiness to his cheeks from the sake, but no drunken stagger. His posture is rigid.

Hawks smirks and leans against the wall with him. "Maybe I came out here to see if I can bum a smoke."

Enji's eye twitches.

Hawks nudges him with the edge of his wings. "That's what you came out here to do, isn't it?"

"Fresh air." Enji mutters, even as he pulls a tin from his pocket and opens it to reveal what Hawks had always been suspicious of. He hands one to the blonde and snaps his fingers together to light the flames at the end.

Hawks feels his knees go weak.

Enji lights his own and breathes in deep. Practiced, familiar, and relaxing by the second as the nicotine floods his system.

Hawks doesn't carry the same ease as his lungs burn from the cold and smoke. Hawks coughs through his third inhale, while Enji smirks beside him.

"What gave me away?"

Hawks clears his throat. "I've spent enough time around you to know the smoke from your quirk, and this scent."

Enji hums. "So you've been spying on me, then."

"Call it curiosity, more like."

"Well, it's a bad habit. Not becoming of a hero."

"I dunno, I think I like seein the humanity in you." Hawks wiggled his messy brows. The scars on his face echoing Enji's own. "If this is what calms you, then it's really tame compared to-"

Hawks loses his train of thought when Enji exhales another puff of smoke from his lips.

Enji finishes the last of his cigarette and stubs it below his boot. "Are you going to finish yours?"

Hawks' eyes are still to his mouth when he shrugs. "I prefer menthols."

Enji takes the cigarette from his fingers expertly. "Is that so?"

Hawks feels his heartbeat quicken.

Enji has been doing his own amount of observance and noticed Hawks zeroing in on him, focused where others would shrug off his mannerisms.

Enji takes a long drag of the cig and closes the cold distance between them, warming Hawks' lips with his own when they press together.

Hawks is too stunned at first, but his body melt against the concrete wall when his lips part to the warmth of Enji's kiss. He sucks in the smoke; lets it burn and warm him, /consume/ him in all the ways Enji's fire does.

Enji pulls back in amusement when Hawks gasps.

"Good birds dont waste what's given to them." Enji takes a final inhale of the cig and drops the remains to the ground.

Hawks pulls him in desperately to choke on the burning, cloying scent of it. Enji goes willingly, the kiss messier this time with Hawks' eager arousal.
