Angel or Devil [Sana x Male Reader]

Part 1: First day

Sana PoV
Starting my first day in a new school abroad is one of the scariest experiences I could ever face. I don't like introducing myself in front of a class of people who stare at me, it makes me really anxious.

On the first morning I was up really early and had already prepared myself for the day ahead, I was eager to start but nervous as well. I got dressed into my new uniform.

I eventually left the house and took the long way through the park to my new school.

As I passed through the park, I sat on the swings and looked out at a pond by some trees, I watched as a leaf glided onto the surface of the water, sending ripples outwards. The sight of this accompanied by the sound of the birds chirping made it clear to see why anyone would love it here.
For some reason this park gave me a major feeling of Deja vu, like I had been in this exact spot before. It felt odd, but I didn't mind it, it was actually quite comforting.

After a while I left the park and continued walking to school, the spring made for the perfect time to walk around the town, everywhere you look there would be some type of plant or flower that just radiates beauty.

I arrived at school right on time and got myself familiarised with the layout of the building by looking at a map. It wasn't very helpful because the tiny font made it impossible to read, but there were some things that I could make out from the map.

I had found my way to class and I knocked on the door, I peered into the class from the window and saw the students jotting down notes. The teacher then came over and opened the door.
"You must be Minatozaki Sana."
I nodded
"Great, I'm Miss Min, I want you to introduce yourself to the class, with a nice big voice."
"Ok, hello everyone my name is Sana and I just moved here from Japan, I hope we can be great friends." I said quietly
The class didn't care and kept writing, I then turned to Miss Min
"Can I go and sit in my seat please?"
"No problem, you can sit in the empty seat next to Nayeon. She's the one daydreaming over there." Miss Min said
I nodded and took my seat

The first lesson wasn't near as hard as I thought it was. As soon as the lesson ended, the girl named Nayeon instantly turned to look at me.
"You're cute, so what's your name newbie?" She said
"I'm Minatozaki Sana, it's nice to meet you."
"Sana Huh? The name's Im Nayeon, and I'm gonna be your friend."
"Umm....ok. So I'm new here and I'm not really sure what to do now."
"That's why I'm here, I'm gonna help you throughout your time here. And right now is break so let's go."
"Thanks! I appreciate it!"

And so Nayeon helped me get up to speed on everything, we went to our lockers which were conveniently placed next to each other.
"So, you listen to Kpop?" Nayeon asked
"Sometimes, it's really catchy."
"Agreed, what about dramas?"
"I watch them all the time."
"Ok , what about anime?"
"What kind of dumb question is that, of course I like anime."

A presence then became known throughout the corridor as everyone looked in one direction at something, the halls became shrouded in whispers. A group of seven people made their way through the hall.
"Who are they?" I asked
"The student council,
