Stalking Someone New(Yoonbumxreader)

"What's going on here?"

Readers POV:
"What's going on here" y/n said.

Now let's start from the beginning so you know how I got in this situation.

I couldn't sleep last night, I woke up around 3 and I couldn't fall back to sleep so I stayed up watching television until morning. It's not like I have someone home to tell me not too. But besides that I also had some homework cause I go to Sungsoo University and the work from there can really take a...
-Ring Ring Ring -
"Hey dad what's up" y/n said.
"I just wanted to check up on you, are you doing fine, have you ate, did you take your pills" dad said like if he was in a rush.
"Like you care *rolling eyes*" y/n thought. "Um. Yeah I'm fine dad , I have been eating, and I've told you I don't need those anymore" y/n said getting annoyed.
"You have to take them Y/N ! Don't say you don't need them cause you do, so just do it please - Sorry I have to go I'll call you when I can, bye"
"okay b-" and he hung up ...
He always does this ! Asks about me then not even a minute later he has to leave. Whatever it's not like I'm not used to it .. it's just so annoying every time. Let's just eat and .. should I take it , they always make me feel so weird. I don't even remember the times were I didn't have these pills... that was back when... it's like those memory's somehow vanished. It's like I lost 3 years of my life but it doesn't matter now, that's all in the past. I'll just take it and leave.
*At school*
I'm not really known here at school but I do smile at anyone who looks my way because I wouldn't want to be rude. I may not be as popular as other but I'm also not a ghost. I would say I'm in the middle but leaning more towards a ghost. Having to smile at everyone can be exhausting some days but I don't want to leave a bad impression with people so I'll smile.
*In class*
"Y/n come here to get your paper back" the professor said.
"Yes Sir" y/n said.
Class can be boring at times but it's not like I hate it , it gives me something to do. I have so much time on my hands that I start doing the work for the following week because I have nothing better to do.. it's like I do it for .. fun!
*After school*
I always stay later at school because I don't like going home right after because walking into a house with no one there is a bit .. lonely and then staying there having nothing to do is boring. So to pass time I usually go visit different stores or I go to different parks just something to pass the time. Today I decided to put on my earbuds to listen to music while I sit on a bench at the park I always go to.
And when I opened my eyes it was pitch dark
"Shoot ! I need to go back home" y/n thought. Waking back was nice the fresh air was blowing on my face and the stars were beautiful.
(No no .. it's okay I'll be on my way now bye have a nice night)
A heard a scared voice .. I have to check what's happening. When I turned the corner I saw a man grab a guys wrist and it didn't look good, I have to do something !
"What's going on here!" Y/n said.
"Who are you!" The guy replied aggressively.
(Come on y/n THINK - y/n thought)
"Me ? Who are you! Your scaring him! If you don't want a problem with me you better leave" y/n said in a confident voice. (Omg this is scary.. keep your cool y/n)
"Whatever ! It's not like I wanted him that bad anyways" the guy said even louder then before.
(The guy walks away)
"Hey are you okay?" Y/n said in a relieved voice.
