"we have some... Weird news" hanji said to the brunette boy sitting in front of them. Levi seemed uncomfortable, he moved quit a bit in his chair and he tried not to look at eren, almost as if he was embarrassed. Which made eren even more nervous and embarrassed himself. "So, we all know you got your first heat a few weeks ago" hanji cut the tension as soon as she noticed. "First congrats! You are officially an adult omega" she smiled widely, though in eren's eyes there was nothing to smile about. "Second thing i... We.. have to say, is that your heat came very early compared to the average omega. Omega's first heat is supposed to happen between the age of 16 and 18, while you are just 15." The nurse seemed kind of concerned. The raven teacher bit his lower lip, stopping himself from saying what he wanted. "I must leave." Were the only words escaping his mouth. "Wha?? Sen.. sensei wait!" Eren said without thinking, levi's presence was important to the kid for a reason. "Levi, stay. This is no topic to joke about" she said and glared at levi, her glare made him sit back his chair, but the more the time pass the more nervous levi became.  "On top of that" hanji kept talking "your cycles have been extremely irregular" she sighed "while you were sleeping the other day" she refered to his first heat "i took a blood test to examine your cycle, but i still cant point the problem out" she said and took a piece of paper out of her pocket. "Hanji, i must leave!" Levi said again, this time his face was flustered in red and his breathing was uneven. "What... Eren, are you in heat right now?" Hanji turned her gaze to the young student. "N-no? I dont think so... My last heat was two weeks ago, so i got two more weeks for my next one" the confused kid say, wondering what is happening to his homeroom teacher. "Hmm? Are you sick, levi? Is that the case?" She asked as she nudged the man's arm, but he slapped her hand out of instinct "fuck, cant you tell?? His pheromones are all around!" He crumpled as if his stomach aches. "I.. i dont smell anything? Amazing! Could it be? " She got excited, like discovering something completely new to the science "eren, can i have another blood test? Levi you stay here!" She said and cuffed the alpha to the metal bed. "Wait... What pheromones does mr. Ackerman is talking about? Only alphas can sense these right?" Eren asked as he got pulled by his arm to the nurse's desk. "What, levi didnt you tell them already?" Hanji asked as she inserted the needle into the other's arm. "Your teacher is an alpha, as you can say". Levi raised his voice just a little "oi, dont tell unnecessary things" his husky voice was kind of shaky "bring me my kit. It's in the beg. Please" he gazed over to his bag that was too far away from him. "Not yet! I need to test this" the nurse said. Though few moments later levi faded away and could not remeber what happened. Eren, on the other hand, remembered it perfectly. From the moment levi stopped talking, his mouth dropped saliva and lather, he struggled the handcuffs and it almost seemed like the bed was about to break, his eyes were full with crazyness and he didnt seem like himself. When eren gazed into his teacher's eyes his heat suddenly came and pain rushed through his body "h-hanji?" He muttered with fear as the look of the alpha paralyzed. That moment eren felt fear, stronger fear than ever, like he was going to be killed, like he was going to be raped, impregnated and slaughtered to many pieces. Hanji finally finished the blood test and noticed that she couldn't take the risk any further. She took out two syringes filled with thick liquid. She injected the first one to eren and the second one to levi. She covered her mouth and nose with thick fabric "give it a few minutes, it will work. I must leave before it will be too dangerous. Dont get close to levi!" She said and escaped the room slamming the door behind her. Eren fell on his knees and his vision faded away into a black void. The next thing he remembered was waking up in a bed, not his own bed and not the bed in the nurse's room. "W-where am i? Ugh!" He opened his eyes slowly. His vision was still blurry and he felt like someone hit his head with a hammer. "You are at the hospital, dont worry help is coming" a familier voice said. "A-armin?" He muttered but before he could say anything else another loud voice came from outside the door "EREN! EREN?! OI LET ME IN YOU.." the door was kicked open "eren!! You are ok?! I heared what happened!!!" Mikasa said bursting into the room. Nurse hanji didnt tell anyone the truth though. Mikasa was telling how everyone is talking about eren's fainting problem because of anemia, although both eren and armin knew this was no anemia.
In another room hanji sat right next to a bed where levi was. "You are such a strong being levi, stronger than any other alpha i knew" she said. "Tsk. It's your fault im here! You should have listened to me" he said angrily, not actually sure what happened.
"You dont remeber do you?" She asked smirking, playing with a pen. "Remember what?" Levi asked, with a little wonder in his voice. "Hmph" she giggled "you broke the handcuffs, poor eren" she said.
