Okay, so the plot for each couple is basically based on 5SOS songs. Everyone is a high school student and the boys are all in a band.
Calum/GF- Try Hard
Calum's girlfriend is the type who doesn't give a shit about anything. She's basically the most popular girl in school along with her best friend, Michael's girlfriend. Calum has had the biggest crush on her for over a year and he does everything he can do to impress her but she ignores him. One day, Luke convinces him to ask her to one of their gigs and she says yes. So Calum has to impress her basically and the band sings Try Hard and Calum says something along the lines of "I wrote this song about a very special girl who barely knows I exist but I was lucky enough to get her to come to the gig." and awe and basically they just make out and shit
Michael/GF- Voodoo Doll
Michael and Michael's girlfriend basically act like they hate each other, she always teases him a lot about his hair and stuff. But they have the biggest crushes on each other. She goes to the 5SOS gig to tease him about it and stuff yeah, but Michael has written a song about her and she's like awe bae and they make out and stuff then the next day in school, she goes back to being a lil bitch and Michael is like wait what and she basically just plays around with his feelings. By the way Michael's GF is best friends with Calum's GF
Ashton/GF- Heartbreak Girl
This one is pretty obvious, Ashton's girlfriend has just got out of a really bad relationship but she still isn't over it. Ashton is her best friend and she cries her ass off to him every night and Ashton really likes her and he'd do anything for her and he invites her to their gig and they preform heartbreak girl, which Ashton wrote about her and she's like "who did you write that song about?" and he's like "uh..you" and she's like oh and they're all like I love you blah blah blah
Luke/GF- Unpredictable
Luke and his girlfriend have been best friends since birth, but her mother recently died of cancer. She becomes extremely quiet and is diagnosed with depression. She doesn't like to do anything and only leaves her house to go to school or to Luke's and basically Luke wants to make her happy again and he does everything he can eg. going out late with her, singing songs for her, just basically being a fucking cutie and he invites her to one of their gigs and they sing Unpredictable and she's like "did you write that about me?" and he's all like uh huh, and he tells her he loves her and cUTENESS
It starts like maybe three days before the gig?? Yeah
