*jaedens pov*
finn came in my room to talk to me
he and alyssa were goung to raine's cotilion tonight and let me tell you im not super happy about it. but i dont want to go with her. so finn is.
finn: i have a crush on your sister
jaeden: like a permanent crush? or just a crush?
finn: i dont know yet
jaeden: well figure it out, if its small dont say shit. if its big, we'll discuss.
finn: got it. but if i did have a crush crush on her would i get your blessing?
jaeden: i trust you. so maybe
finn: really?
jack: OH SO HE GETS A MAYBE BUT I GET A NO?
finn: fuck off jack
jack: dont ya mean fack??
jaeden: no gay shippery in here
wyatt: jyatt is real
prestyn: THE HECK DID I JUST HERE
chosen: shes everywhere
jaeden: for real tho
prestyn: hey i only have 10 minutes
alyssa: ok thats 3 songs and a hug lets gooo
then alyssa shut her door then opened it and ran in my room then grabbed sophia
and sophia had the widest smile on her face
they ran into her room and we heard them screaming grenade, call me maybe, and the phineas and ferb theme song
chosen: its so cute how alyssa and prestyn are including sophia in everything
jaeden: yeah. yeah.
my mind kept going back to prestyn
not gonna lie i was falling for her all over again
but was it the best idea? shes my sisters best friend. 10/7 chances alyssa would be on her side no matter the problem
and it would crush her
but its true
jeremy: jaeden?
finn: helloooo?
alyssa: ohmygod can you guys shut up
wyatt: he wont get out of his thoughts
she came in and slapped me and i jerked away
alyssa: now shut up please
sophia: youre so mean
prestyn: thats the best part
she just laughed and prestyn laughed
we made eye contact and smiled at eachother
everyone smirked at me
jaeden: oh shut it

prestyn: so you ready for your date?
