Izuku took a quick shower before leaving the room. He needed to get rid of the scent of his slick on his body. He also put back scent blockers and wore another set of clothes.

Katsuki changed his clothes too, since Izuku's arousing pheromones had slightly stuck on the fabric. They couldn't afford to take any risk.

When they finally were both ready, they decided to go to the common room. The other students had surely already finished All Might's course and were probably hanging out together in the lounge...

"Midoriya!"

As soon as they entered the common area, all eyes immediately turned to Izuku. People noticed the omega was back and quickly surrounded him, questions firing from every sides.

"Are you feeling better?" Iida asked, his voice filled with honest concern.

"What happened to you!?" Ochaco inquired.

Izuku felt quite overwhelmed by the sudden attention he was getting but he was agreeably surprised by his classmates's worry.

"Oh. I'm feeling better, don't worry..." The omega timidly answered. "I sometimes get lightheaded when I use my quirk too much, it's nothing serious..." He explained, a soft blush taking over his features when he thought about the real reason why he had had to promptly leave in the middle of training...

"Your quirk is amazing, man!" Kirishima suddenly exclaimed. They had all seen how easily Izuku had kicked Sero out of the circle and they still couldn't get over how incredible it had been.

"Right! I barely even blinked that Sero was already out!" Kaminari eagerly described.

"I didn't have time to see what was coming either." Sero added with a playful chuckle, his comment triggering laughs from the other students.

Izuku also let out a soft giggle at Sero's joke. The omega's giggle sounded so adorable people couldn't help but instantly love hearing it. The cute sound was like music to their ears; they definitely wouldn't mind hearing it every day of their life...

Katsuki made sure Izuku was alright talking with everybody before leaving for the kitchen.

The alpha couldn't care less about making small talks and being friendly with others. He instead found the kitchen and started to open cupboards, looking for food. All the energy he had spent taking care of Izuku when the omega was in heat had made him quite hungry...

Searching for some spices, he didn't notice the other person who had followed him to the kitchen, until they suddenly spoke out.

"Why were you coming from your room and not from the infirmary, where you said you would take Midoriya?" The person bluntly asked out of nowhere.

Katsuki promptly turned around at the sound of the voice coming from behind him, his crimson eyes landing on the bicolored alpha who had used an impressive ice attack during the one-on-one battles.

Katsuki frowned as he wondered what Todoroki's deal was. "The nurse told Deku to get some rest in his room." He answered, his tone cold and hard. He didn't like one bit how Todoroki wasn't minding his own business and instead asking questions that didn't concern him at all.

"Really? I think you didn't go to the infirmary at all." Todoroki unexpectedly replied. His face and tone were void of any emotions, therefore Katsuki couldn't know what his intentions were at all.

"Actually, I don't think the reason why Midoriya suddenly didn't feel good was his quirk." Todoroki added and Katsuki let out a low menacing growl at the words. "And what the fuck makes you think that?" The blond alpha snarled, his whole demeanour turning on the defensive. What Todoroki was starting to insinuate was dangerous.

"Vanilla and cinnamon roll." Todoroki simply answered, these few words enough to suddenly silence Katsuki...

It was the scent of Izuku's slick.

"I can still smell it on your fingers." Todoroki added. He didn't need to be a genius to understand what it meant. Izuku was an omega. He had suddenly gone into heat during training and Katsuki had helped him.

Todoroki was a dominant alpha, and dominant alphas had an enhanced sense of smell. It was no wonder he could smell Izuku's slick... but Katsuki hadn't thought about this at all.

"Fuck." The blond alpha cursed under his breath. It was bad. Someone had already discovered Izuku's secret, and out of everyone it had to be Todoroki. Things weren't looking good. Katsuki had no idea what Todoroki intended to do with the information, but he didn't want to wait to find it out. He needed to react and he needed to do it now.

He was actually about to, when Izuku suddenly appeared out of nowhere.

"Kacchan!" The omega eagerly called out. "Everyone wants to play at truth and dare to get to know each other! Come play with us!" He exclaimed, his emerald eyes sparkling with excitement.

However, as soon as he noticed the growing tension between the two alphas, his smile immediately faded away to be replaced with a worried look. "What is it? Is something wrong?" He asked, his voice filled with concern. Katsuki looked like he was going to murder Todoroki and Izuku was almost afraid to learn what was going on.

"He knows." Katsuki only said, his crimson eyes not leaving Todoroki even one instant as he spoke.

Izuku didn't need to ask to know what Katsuki was talking about. He immediately became incredibly pale, his beautiful emerald eyes widening in fear as he looked at Todoroki. "H-he knows..? H-how?" He asked in a small, trembling voice.

It couldn't be happening. They had been careful and nobody had seemed suspicious until now. The omega didn't understand how Todoroki could have figured things out with only what had happened...

"The smell of your slick." Katsuki answered and Izuku's whole face turned a dark red at the words, deep embarrassment and utter mortification promptly taking over him. As if Todoroki knowing his second gender wasn't already enough, he also knew what they had been doing during his heat...

Things couldn't be worse.

"Please, don't tell anyone." Izuku suddenly asked Todoroki. His voice sounded weak and desperate, even pleading. "I'll probably get expelled if it's known, I'm begging you." The omega implored.

He really couldn't afford to be expelled from UA. He had worked so hard to get where he currently was; he couldn't lose everything now. Not when his dream of becoming a hero had finally became reachable.

"I'll do anything you want." He despairingly said.

"Like hell you will." Katsuki promptly replied. There was no way he would let Izuku do anything Todoroki wanted. They didn't know what the bicolored alpha would ask and Katsuki preferred not finding out about it. There was too many things an alpha could want from an omega...

"I won't tell anyone." Todoroki suddenly stated.

Izuku's emerald eyes got wide at the words, surprise and hope shining inside the two green pools. "Really?" The omega asked in a voice filled with expectation.

"I don't care if you're an omega." Todoroki answered. His mom was actually one; he had respect for omegas. "As long as you deserve to be in the hero course, I don't see the problem." He said.

Izuku couldn't believe what he was hearing. Knowing someone was judging him for his value and not for his second gender meant so much to him. The omega couldn't even express how grateful he felt.

"Thank you..." He murmured, his tone full of the overwhelming emotions surging inside him.

"But you should be more careful." Todoroki unexpectedly added. He looked right at Izuku, his whole demeanour serious as he spoke his next words.

"If I was able to figure out you were an omega, other will too..."
