Canary was sure Killua was careful on how often he let those moments happen, letting them be as few and far between as possible so they'd slip under her radar. He didn't want her to ask about it. Killua didn't have to say it aloud for Canary to know. She just…knew. And so she respected his wish for her to not poke her nose in uncomfortable territory.
She always knew when he was about to lapse back in to that mysterious part of himself. There would always be a strange feeling in Canary's gut before it happened. It would happen somewhere between all the thrusting and panting and screaming and moaning. Killua would then suddenly stop, eyes losing their mischievous, vibrant luster and suddenly hazing over. His fingertips would then gently ghost over all the scars marring her skin, each finger stroke more gentle than the last. Canary knew that if her gaze hadn't been trained so closely on his eyes that she would've missed the flash of anger in those blue orbs.
Canary always stayed quiet during those moments, except for the one time where she said in a soft voice, "Killua?" She suddenly couldn't feel his thumb stroking the scar a little ways above her breast. Soft brown eyes met intense electric blue ones. The way he was looking at her made her want to shift around a bit but she managed to stay still.
The attractive woman reached up to cup his cheeks. "Killua, do you wanna stop?"
Canary hadn't been able to make sense of his reaction to her question then and still couldn't now. Her boyfriend could be rather unpredictable sometimes and had chosen that moment to be exactly that by letting out a laugh. Canary blinked, gaping confusedly up at the man. She couldn't help but flush in both embarrassment and confusion as Killua nuzzled her cheek affectionately, bringing his head up to beam down at her before placing a kiss on her forehead. The man rolled off of her before raising himself up off their shared bed. Feeling unusually self-conscious of her naked body, Canary wrapped the blankets around her. She looked over at Killua, surprised to see he was still standing in the same spot he had been in since he left their bed. The older hunter had opened her mouth to say something but her boyfriend beat her to the punch.
"I'm gonna go take a shower," the assassin announced.
Canary closed her mouth, silently watching the naked man disappear into the bathroom with a click of the door. She sighed as she collapsed against the pillows and sheets of the bed. She closed her eyes with the intention of only resting her eyes. Sleep ended up ensnaring the hunter in its trap, however with a kiss on her forehead being the last thing she felt before her consciousness finally left her.
