First Class

Aiden guides Serianne through the endless hallway, passing by pillars. He has been working in the academy for 3 years, making him a senior teacher. He teaches Math and Science, which is expected judging from his appearance and the way he carries himself. Full of pride and dignity as if he never made a mistake in his whole life.

Aiden takes a halt and points at the door at his left. He fixes his glasses above his nose bridge as he speaks. "Here is the music room where students study the art of melody and musical performance. We have a lot of talented students who always use this room for practice."

Serianne follows his gaze upon the grand hall which looks like a place of gathering rather than a mere music room. It looks incredible. There are various kinds of musical instruments arranged here. The place offers high quality instruments and audio speakers for maximum satisfaction. Every music lover would want this place.

"You love music?" Aiden asks slowly, probably sensing her locked gaze on that room.

Serianne got caught off guard. She didn't expect a cold man like Aiden to asks about her interest. He doesn't look like he's up for a leisurely talk.

"Kind of. When I was a kid, I used to sneaking out the garden and singing alone. It brought peace into me." She replies while fiddling with her fingers shyly. Thinking back of her childhood memories brings her a sense of longing.

There's 10 seconds of silence before Aiden responding with his lack of emotion. "I see...No wonder." He turns around and continues walking without explaining himself.

"Hey, what do you mean by that?" Serianne protests but she got ignored.

"You look like someone who belongs to the stage. Why didn't you be a music teacher then?"

"Uhh..." Serianne pokes her index fingers together and looks away awkwardly. She might love singing but her voice is not that good. She always got scolded by other angels for breaking the windows. "History and Languages suit me better." She excuses herself and thankfully, Aiden doesn't press further. That man doesn't show much interest in her background anyway.

As they continue touring the building, Serianne senses various kinds of aura. Some of them are neutral, a normal human being while some other— wicked, filled with malice. Devil.

Serianne halts on her feet and looks around with tense. Aiden stops on his feet and looks over his shoulder. His hands are tucked in his black pants pockets.

"Something wrong?" He raises his dark eyebrow and poises her a questioning gaze, one that could melt any woman.

Serianne looks around nervously but she quickly masks her worries with a calm gaze. She manages a small smile.

"Where's the toilet?"

She can sees Aiden squinting his sharp eyes for a bit. He points at the hallway at their right.

"That way. The teacher's."

With a nod, Serianne makes her way to leave, ignoring the curious gaze lingers on her.

Once she's certain Aiden is out of her orbit, Serianne sharpens her gaze and senses. Her angel senses help her detect any malice activities around her. The nearer the source is, the stronger her senses tingle her being. But not all demons she could detect. She can sees evil aura and smells their malice.

She follows her senses until she arrives in an empty classroom. The sound of smoochs and soft moans echoe from inside. With serious gaze, she slams the door open, startling the couple making out on the desk.

"Huh? Who dares to disturb us?" The male student groans and curses. He looks over his shoulder and shoots a glare at Serianne.

"Can't you see her uniform? She's a teacher here." Said the female student, trembling, feeling scared for being caught. Her legs are still wrapped around his waist.

"I don't give a fuck about consequences. Just leave us alone, woman." He snarls, not caring of the death glare coming from Serianne. He continues gripping the girl and nuzzles into her skin as if no one else exists.

Serianne smiles, but the smile spells danger, threatening. She radiates a deadly aura which one can't ignore. She steps closer and regards the trembling girl.

"Young lady, are you certain that the person you're making out with is a human?"

At her question, both the male and female students freeze and jump. The girl looks bewildered. "W-What do you mean?" She stammers.

"I suggest you to run. Now."

"Leave us!" The boy snarls, still gripping the girl tightly to the point of hurting. She winces.

Serianne chuckles slowly and nods. "I see...you're worried that I have found out."

The boy stops. He slowly releases his grips from the girl, allowing the poor and confused human to run out of the classroom.

His demeanor shifts, showing his fangs and glowing dark eyes. "How did you know?"

"Because I'm your executioner, you vile creature." With a smirk, Serianne grabs the cane from her hips, removing the case to reveal the sharp thin blade from within.

Without hesitation, she swings the sword and thrusts into the demon's chest. The demon struggles and writhes in pain like a worm in the heat. Eventually, the struggle stops, leaving scattered dust into the air.

"One down." Serianne whispers, watching the body dissolves into the air. There are probably hundred or more demons hiding in the academy but she's being patient. She swears that she will eventually purge them all including their king.

After making sure no evidence is left, Serianne leaves the classroom and returns to Aiden. However, he's nowhere to be found. It's working hour so he's probably teaching his class now.

Serianne takes out her phone and checks her schedule. Her first class will be starting in 20 minutes. She hurries to her desk to prepare the necessary materials. It's her first time being an educator so she's kinda nervous. But that won't stop her from doing her best.

"Good morning, everyone. Call me Miss Seri. I'll be teaching you History from now on."

Serianne is aware, if she wants to survive, she needs to maintain her professionalism and good relationship with her students. That's why she masks a friendly smile to make her look approachable in her first class. The first impression is crucial. However, the students themselves are not helping.

"Wow, she's cute."

"Bet she has fucked several men before."

"She looks like the same age with us."

"Now, this is interesting."

"I think I want to try..."

Murmurs and catcalls fill the classroom. Serianne tries to stay calm at her desk. Deep down, she is grumbling and cursing, like a ticking time bomb which is about to explode anytime.

'Seriously...what's wrong with this class? No, what's wrong with the students in this school?! Isn't this school is supposed to be prestige?! Why do most of them act like a pervert?!'

Perhaps the spoiled brats got too much freedom that they believe they can do anything they want and get away with it. Well, Serianne is not going to let that one slide. Over her dead body!

She grabs her cane and slams the tip onto the desk, causing a loud thud which startles everyone in the classroom. Dead silent. She smiles sadistically and rubs her cane.

"Let's start the class, shall we?"

It was a mistake. Why did she choose this job again? She had the freedom to determine her future. Like working in a cafe or nurse in a hospital. But instead, she chose to be in this school. And now, it takes every nerves on her body to deal with these flirty and naughty students.

Despite her warning earlier, it's not long before the students become noisy again. It's like they have no respect and never fear of the consequences. They couldn't care less. The school rules don't affect them. Perhaps this is why it's called 'prestige' school.

Fortunately, Serianne manages to survive her first day. She staggers back to her office on the third floor, exhausted physically and mentally.

"Those students...are not demons and yet..." She collapses onto the chair and rolls her head back. Her white hair is messy from today's ordeal. "What are they? Monsters?!" She smashes her head onto the desk. This is what it feels to be a teacher?

Suddenly, the door is knocked. She quickly fixes her ponytail and hair before straightens herself in her seat.

The door is creaked open. It's Aiden. His face is straight and cold as usual. "You okay?"

Serianne tenses slightly. Does he worried about her? He might not look like it but deep down, he's a caring person. Oh god, she loves his virtue. That's such a rare treat coming from a human.

Aiden regards Serianne with serious stare. His hand is clinging onto the doorknob. "Your class is a bit rough from others. That's why the previous teacher left."

"Huh?" Serianne suddenly feels like a clown. Did she got set up? That's why she got the job easily? Because no one wants to teach that unruly class? The feeling of regret slowly arises.

"Regardless, you survived. That alone proves that you're indeed qualified to handle them. I won't worry much after this." A low smirk is carved on Aiden.

Serianne shoots him a glare. She runs her hands over her face and stands up. "Why no one told me about this?"

"It's not compulsary to include students' behaviours in the document. The new teacher must figure it out themself." Replied Aiden. "Moving on, the day is over. Do you want to grab a meal?"

Serianne looks up, staring at him with disbelief. Maybe it's because it's her first day, that Aiden acts kind and friendly towards her despite his cold nature. He's usually a 'couldn't care less person' among the teachers. He's known for his 'emotionless' behaviour but towards Serianne, he is a bit different.

It would be rude to reject his offer so Serianne just nods. She walks towards the door while Aiden keeps it open for her. Outside, they stop. Aiden stares down at her with a frown.

"What's wrong?" Serianne asks.

Aiden slowly leans in. He reaches out his hand. That caught her off guard. For a second, Serianne thought he was going to kiss her but she was dead wrong. His fingers slip under her necktie, twisting and fixing it in place around her collar.

"...There." Aiden muses and pulls away in satisfaction. He's a perfectionist and dislikes mess. His office is tidy and clean all the time, showing how much he can't stand mess. His colleagues always call him 'Mr. Perfectionist' or worst 'OCD' but he denies it. He thought it's normal for a human being to prioritises cleanliness over anything else.

"Let's go."

"..."

Serianne touches her necktie which was twisted together a minute ago. And now, it looks firm and perfect in place.
