It started small. When he caught you with his oblivious roommate Gomez and his girlfriend Mortica and her sister Ophelia. Isaac had felt something that he had never felt before. Something he thought he could never feel but there it was in black and white.
And from just a simple glance started Isaac Night Obsession with you. Y/n L/n the most beautiful girl he had ever laid eyes on.
It started small with barely noticeable glances in classes you had or across the quad or when you'd visit his bedroom with Mortica. Where you had formally met.
~~
"Oh, Gomez is this your new roommate?" Y/n asked as she stared at the boy at a desk. Gomez pulled back from Mortica smiling.
"Ah! Yes. Y/n this is Isaac Night." He gestured towards the guy at the desk.
"It's a pleasure to meet you Isaac." Her soft silky voice said.
Isaac turned his head upon hearing his name. And his ticking heart stopped at the sight of her. She was the most beautiful creature he had ever seen with piercing eyes, flowey hair, heart shaped lips.
"Pleasure to meet you as well." He said as he moved over towards her. "What did you say your name was?"
"Y/n." She replied back with a small smile.
His lips pressed together in a slight smile as his eyes trained on you as he repeated the name in his head.
Y/n

After that day, he learnt her routine. Following close behind her as he took pictures of her. Whether it was in the quad, the lake, in the woods, hanging out with her friends, at the galas or/and formal events or any event that Nevermore had. His obsession with her became so bad that his sister mentioned something after seeing numerous pictures of her scattered around his lab.
~~
"Isaac this isn't okay. I mean do you know her at all?" Francoise said as she looked at all the pictures from nearly a year of Y/n L/n.
The girl she stayed away from for one reason and one reason only. She was a siren. A merfolk who sirens people with their song or voice in general. She's dangerous. Not to mention she hangs out with Isaac's sleeze roomate and his lover.
"Francoise, I know everything about her. She something isn't she?" Isaac said as he looked at the photos he had taken over a course of a year.
Francoise stomach coiled in unsettledness and fear. She knew that her brother became obsessed with things especially when it came to science or helping her but seeing it form onto a person that was her or blood related made her feel uneasy. She wondered what he would do? Would he go to the same lengths as he does with science and a gnawing feeling told her it was much worse that these photos aren't even the beginning of it.

A year. That's how long she felt the eyes of another person 24/7. At first Y/n thought it was a prank or that she was being paranoid but now. It had to be something more.
Why did it take her so long to piece it together you may ask? Well she did evidently try to mention it to her friends but they all call her paranoid or something along the lines of "your practically famous from your family's name" and it was true her family went all the way back to the original sirens that once swam the sea but it shouldn't be that big of a deal but to some it was. It made her 'royalty' at Nevermore just like Morticia because of her terrifyingly self appointed mother. A legacy was what you were. But it wasn't just that later on when you would get asked on a date and suddenly something would happen and they'd cancel.
For months you've tried to figure it out but it was no such luck. She suspected Gomezs roommate at first but it could be him. Could it? She thought before shaking the thought away. No, it couldn't be he was always so kind and would even comfort her after her dated would cancel when she'd be all ready to go waiting in the quad. He'd show up either going or coming back from his lab.
Over the course of them meeting they had grown closer. Even shared a kiss a few times during her time of comfort or need. Which made them closer but not at first.

"They're ineffectual morons who don't deserve someone as kind and beautiful as you." He whisper in a slightly dark but comforting tone to you under the pale moonlight that lit up the quad.
She lifted your head and turned towards him. Their eyes meeting in the moonlight glow and suddenly there was a pool whether it was the atmosphere or his words but the next thing she knew was their lips meeting in a slow soft deep kiss. The kind that you yearn for. That you see in movies with so much passion but doesn't show it. It's not intense passion but a soft one. Like a flame burning in a candle.
~~~~~
Ever since that night she's been avoiding him. Ever since he finally got a taste of her lips his obsession his urge to have her be his grew more and more. Which concerned his sister more and more but she didn't have room to talk falling for a normie.
That night she's been avoiding him at any effort he had. In class she would sit somewhere else, run into each other at the quad or when Gomez and Morticia would be at the dorm she'd leave almost immediately saying she had somewhere to be and in truth he was getting sick of it. So he decided the perfect moment to get her he just had to wait.
~~~
After the kiss that they had in the quad. She's done everything possible to avoid him. Sitting elsewhere in class or even skipping classes to avoid him, dodging him at every chance she had.
She was confused about her feelings. She never had really felt the way she did with him and it scared her. Not to mention she always had the underlying feeling that she shouldn't trust him that there was a darkness to him apart from his clock work heart.
She was buried deep in thought as she walked down the empty corridor when suddenly a hand reached out covering her mouth and grabbing her. She shrieked when she hit the wall eyes closing at the slight pain but her eyes opened to see him. The same person she'd been trying to avoid.
"Isaac? Wha-" "I'm sorry. I just need to see you." He whispered. She looked into his eyes to se something she couldn't quite put.
"Why have you been avoiding me? Is jt because of the kiss? Do you regret it?" He asked as his hands slid down her arms.
"I-I don't regret it.. it's all I can think about really." She admitted tearing her eyes away from his but as she did a dark smile appeared on the tall boys face. "The reason why I've been avoiding you is because I'm conflicted and my feelings for you scare me."
Isaac stared at her for a moment his face still upon hearing those words 'feelings for you' . She felt the same way. He lifted chin making her look at him as he planted his lips on her in a deep kiss that made her legs go weak.
"You have no worry to fear. My feelings are just the same as yours." He whispered, when he separated from the kiss. Her eyes glimmered in the rooms glow.
He trailed slow light kisses to her ear that made her shutter in what she did not know. As he whispered "be mine."
She looked at him in shock. "Isaac I-"
Before she could say anything his lips found hers again making her thoughts dissipate before nodding her head 'okay'. Sealing her fate as she became his.
The only thought on his mind.
My girl. My Y/n. My sweet obsession..
