S/n= big sis name (or just make up one if u dont have one)

Y/N POV

I was walking to lunch at my school when I saw my sister with a guy..shes a few grades above me but we still hang out sometimes at school. Anyhow- she looked like she was having a nice time...'does my hoe of a big sis have another boyfriend?? Geez you think by now they'd learn...of course he looks new..poor guy. Anyway he looks nice than her last one..Zantiel...he was a creep always staring at me, asking me things, buying me things...its like he thought if he could get closer to me he could win S/N over??? Idk but imma eat now after this long ass thought rant' I sit down and was about to start eating until I see S/N and the new boy sit across from me..."And this is my little sibling Y/N!" She cheers smiling at us both. I nod towards him and continue eating while S/N tells us about each other...like you think hes permanent?? Like the others...?

Zantiels POV

I saw them across the way in the lunch room...my EX S/N and her amazing little sibling...with a new guy?! 'Hes going to taint MY Y/N before i can even speak to them again! I have their number still but...I need an excuse..maybe I need something from S/N? Right I left a hoodie there I think...i can use this! Maybe i can take them now...no too risky..I suppose they'll be alright as long as he doesn't try anything.'

Y/N POV and a □timeskip■

Were at home now and I got a text from someone! Maybe its Fate! Shes really pretty and likes all the things I'm into...I think I might like her but itd be awkward to tell her...anywho- I check and its..not Fate...ew its Zantiel...why would he need to ask me something? NO WHY IS HIS NAME SAVED LIKE THAT- AOQJWJWJ DAMN ME-

Zantiel♡: Hey I think I left my hoodie there..can I come get it?

Me: Sure just be quiet when u do S/N has a new guy over and I'd like to not bug them or make S/N mad..u know how she gets😒

Zantiel♡: Yeah lol I just wanna catch up and grab my hoodie I'll be out of there in a lil bit..omw now.

Damn..hes really coming over huh? I suppose I should get it...I walk into S/N room and grab the hoodie there down in the living room coming to her room in like 5 mins...I know cuz she does this with every boy..same routine. They enter and I wait for Zantiel...I hear a knock and let him in dragging him quietly to my room and closing the door before muttering a small "get comfy if were gonna talk" he sits on my bed and looks around before turning to me who just sat down.

"Nice room.." "ah thanks..."  then he just asks how I've been and what I like and stuff like that me asking back..hes not so bad when hes not around S/N I guess...."Ah! I got you another gift.." "you did?? You know since you guys arent together you dont have too anymore-" " I know I just..want too..so here.." he pulls out a bag I didnt even see and he pulls out a cute outfit..

For reference:

(I thought the outfits where hot so- if u dont like them you can always change it!)

"Uh..you know my size??" "Mhm S/N told me while she ranted at some point..do you now like the outfit I picked?? I can get you a new one-!"

"No! I uh...I mean...I really love it and appreciate it Zan...thanks..." WHY TF DID I GIVE HIM A NICNAME??ANKWJWJW- "Ah so you do! Thats wonderful I was hoping you would N/N!" Wheres his creepy ass personality?? Like did he do a complete 180?? Huh? I like the fact I'm just now noticing this- I'm suddenly pulled into a hug by Zantiel.."I'm sorry we cant talk as often as we did when me and your sister was together-" I'd prefered it that way please stop and go away with your new fake ass personality- "- but it's ok! I'll make sure now we can spend time together all the time I'll sit with you at lunch we can go hang out around town! Stuff like that!" "Like dates??" Fuck why did you ask that?? "Yeah! Maybe we can hug more like this too!" He nuzzles into my hair and I'm internally panicking...why would he want to hang out with me?? and like on dates and stuff? I'm his Exs little sibling...this isnt supposed to happen please leave us alone...

Next thing I know I'm giving him a goodbye hug at the door and agreeing to meet up tomorrow..yayy...

It's the next day and its been ok...we've gone to a movie..we see Fate and I was a blubbering mess..I could hardly speak I was so nervous around her! I thought I saw Zantiel glare at her but I dismissed it as a misunderstanding!

Fate was found dead yesterday...I dont know what to do now..Zantiel was there for me...I'm happy even though him and S/N relationship is complicated we can be friends..dont tell him though..

I dont know where I'm at I'm blindfolded and tied up...I cant move the ropes are tight. I hear someone!

Its-

"Zantiel?!-"
