(a demon's guide to stealing a soul- and maybe a heart)

That's it. That's the story.

Some people long for a guardian angel. However, I, a demon, do their job for them. Call me a guardian demon or whatever. That's not my job though. I wasn't tasked to do it.
I know you have some questions. Well, I'm from hell- obviously, but to fit in with civilian life, I say I am from Norway. Because absolutely no one that lives in Hong Kong is from Norway. I live with my brother—— a fellow demon, and I go to school in Hong Kong. I am a few thousand years old, and since demon forms cannot pass through the barrier without a vessel, I took the vessel of a 15- year-old boy, 1) to fit in and 2) to be able to get to the surface.
I know most people that have met our kind say that we are selfish assholes, that we don't feel anything for anyone but ourselves, but that's only our survivalist mindset. Because how else are you going to survive in a world that's "kill or be killed"?
The reason why I chose HK was because of the stressful atmosphere. Their teenage suicide rates are through the roof. The more depressed people are, the more desperate they are to "find a saviour", the easier it is to manipulate them, the more likely I am to get a deal. 
Even though this is a lengthy and exhausting process, in the end, it's worth it. Because children's souls are the sweetest.
Just as I was convinced I made the perfect choice of the place to find a victim, I took a double-take when I got to the school. I wasn't the elite, top tier of humanity back then. No way I could've gone to school. Unlike many, I don't have strong desires to be knowledgeable. Yet here I am.
The school was huge, the largest in Hong Kong in fact, yet it felt constricting at the same time.  I've never seen these people before, yet somehow they were all familiar faces. Could it be because they looked the same as newcomers to hell? No, because they've been at school for their entire lives.
If school was the miniaturised version of normal society, then the future of humanity is doomed. Few of the children are enthusiastic to learn, other than which look like they want to die. Everyone is expected to achieve the same standards, which, is such an absurd idea.
Friendships here are artificial. They band together to ally boredom. No one came to me for an alliance. For weeks, kids were looking at me weird. But I wasn't. I was wearing the same uniform as everyone else; I had a big, heavy school bag on my back like everyone else; I was the average height. I even looked into my phone camera once to make sure I wasn't in my true form. So why were they refusing to talk to me, or staring at me like I was a unicorn?
"Like, you need to step aside or something, dude. You'll get trampled by everyone if you just stand in the middle of the road." A voice with a vaguely British accent rang through my left ear. I looked over to see a boy slightly taller than me. I've seen him around. He wears a long-sleeved jacket every day even if it's 30 degrees. His face was handsome, but the first thing you'd notice is his thick eyebrows, which I thought was quite unusual.
"Oh sorry man," I said, following him into his classroom once I recognised him from my class.
"He'll do." I thought to myself.
"Say, like, are you new here?" I nodded.
"Just moved here. It's a bit nerve-racking going to a completely new environment, you know?"
Our conversation had some "mhmm"s scattered here and there, but to spare you the trouble, I deduced it to- his name is Leon, he's half- British, half-Chinese and didn't really fit in with the others, which he claimed was due to just "people not comprehending his awesomeness". I can't help but think that there's a reason more disheartening that he's not telling me. Good.

Becoming acquaintances was more straightforward than I thought. When two loners join forces together, they become the human equivalent of the term "alone together", which became what we were known around the school. We made an odd pair— platinum blond against brunette, death metal and classical music versus emo- rock, but somehow I found him approachable. Surely, someone I found so likeable shouldn't be avoided by everyone else in the form?
We had lunch almost every day together. On Thursdays, he has to go see the councillor, so I eat alone. We have certain classes together— like History, Math and PE. Though he never seems to be enthusiastic in PE class (yeah, because he's always enthusiastic anyways.), and he seems to hate swimming. Or maybe he doesn't know how to swim? Every time we have to swim he makes an excuse to the teacher like, "I'm not feeling well" and every time we play ball or something he still wears a sweater ?? Like how.
I've been invited to his home a couple of times, but I haven't accepted the offer yet. It just feels like moving too fast, and I don't wanna mess anything up. Do you have any idea how difficult it was to set a perfect cover-up for who you actually are?
