Lee Sa-young's eyes narrowed dangerously as the sweet scent (omega, the part-timer... was he in heat?) led to a particularly seedy part of Seoul, a part where no self-respecting omega with a choice would go to.
But the scent led that way. Even if the scent in the restaurant was faint, only just blossoming, Lee Sa-young could smell it. An omega going into heat. His part-timer omega going into heat. And then heading outside without him.
A low growl unconsciously escaped his lips, but Lee Sa-young could hardly care about losing control when control was already so fast to evading him because how dare he. Did Cha Eui-jae not know that he could only be touched by him-?
Lee Sa-young tried to remind himself that Cha Eui-jae was not his omega. In fact, he did not have an omega. (He once thought he wanted J as his omega, but no one knew what second gender the mysterious Hunter had and Lee Sa-young wasn't sure exactly the type of relationship he wanted with J yet, only that he wanted to one day open the rift and find him.)
But Cha Eui-jae was an omega. Everyone knew it and Lee Sa-young's alpha must have confused his interest in the mysterious part-timer as interest in him as a mate because it was getting harder to concentrate, harder to remember that he was not following after the trail because he wanted to knot the omega for his heat, but because he was curious and admittedly concerned.
But he was only concerned because Cha Eui-jae should have taken suppressants.
Surely, the popular hangover soup restaurant was not so poor that Cha Eui-jae couldn't afford heat suppressants.
Why was he going in heat and why, if he wanted to go into heat instead of take the damn pills, did he go into this part of the city where only the poorest omega with no access to suppressants would go to spend their heat?
(Because here were the glory holes - places where omegas would stick their lower half through holes in the walls for any passing by alpha to fuck.)
There were better places like rental heat rooms, high quality brothels, trusted alpha escorts people could make appointments with online.
Lee Sa-young tried to ignore how his alpha cried for blood at the thought of each one. No good. None of them were good options. How dare his omega go somewhere else than his place. How dare someone else touch his omega-
Lee Sa-young's vision turned red when he smelled his omega in full-blown heat, rushed in and threw back a flimsy curtain, and saw someone in his omega-
-
When Lee Sa-young came to, snapping out of his rage, he found himself sitting on the ground, buried to the hilt in Cha Eui-jae, the omega sleeping in lap.
The wall that had once been used as a glory hole was completely gone. There was also a black puddle on the ground nearby that looked suspiciously like when he melted Awakener criminals and mutated drug addicts.
He even vaguely remembered melting the alpha, but that memory was completely overshadowed by the overwhelming memories of scraping all of the dead alpha's seed out of his omega, punishing his omega with slaps, and fucking him again and again, biting him and marking him until Cha Eui-jae was undoubtedly his in every way. The wall stood no chance when Lee Sa-young in his rage wanted to mark Cha Eui-jae on the neck - and he did to Lee Sa-young's glee and dread-
"Shit!" Lee Sa-young jolted as he remembered something, almost standing up if it weren't for the omega in his lap. Examining Cha Eui-jae quickly, Lee Sa-young sighed in relief when he realized that the omega hadn't been completely hurt by his S-grade strength (he was really an unregistered S-grade Awakener then) nor by his poison (Lee Sa-young stared. How? Even Jung Bin would get burned by him).
He touched him with hands still soaked in poison, even kissed him and bit him and knotted him, and yet the omega was sleeping peacefully after having gotten enough to satisfy his heat.
"...Tsk." Lee Sa-young clicked his tongue. "Why are you even here?" It was a big mess, but he wasn't that much of a jerk to not realize that he was a large contributor of it. "Just take your damn suppressants." He grumbled before realizing that he actually did remember asking that question to the omega while growling at him.
It seemed like the part-timer had at least an S-grade poison resistance skill that also canceled out the effect of suppressants.
"You are so much trouble." He complained, but somehow he couldn't feel bad about everything. For some reason, he really liked this omega, so much so that he lost himself in rage. He couldn't get rid of him after their deal was over either, Lee Sa-young thought as he touched the mating bond. He wasn't that much of a jerk. "Damn it. What would hyung think when he finally returned?"
