Shitty Teen Squad/Hellion Trio AU
Where they’re college classmates that take a few subjects in common, but have their own subjects to study on their own as well.
Gradual friendship where they bond and bicker like Soft Competitive Young Men and eventually they all decide to rent a room together and be room mates.
...only to slowly fall in love with each other throughout the years, the emotional and sexual tension between them piling up more and more until it becomes an ever fluctuating love triangle that’s had its fair share of Unrequited Love between the different pairs between Badd, Genos, and Garou.
It eventually comes to the point where they’re out of the trend of loving Just One and into I’m In Love With My Two Best Friends, but considering the rejections, the attempts to still be friends after that and recovering from them, they feel like that dating each other is a Bad Idea that they Shouldn’t Be Getting Into.
It doesn’t stop them from feeling jealous or longing for the other and feeling like they can’t say anything that’ll ruin the lasting bonds as friends that they managed to salvage from the frustrated tears, the self loathing regrets, the hoarse heart to hearts and confiding that cruelly made them feel closer whilst making them feel better about having the courage to confess. It doesn’t stop the hurt in one of their chests as their crush yells and cries into their shoulder after being rejected, not realising that their Confidante loved them too.
Unrequited Love, Spicy Action/Romance/Drama (the action part coming from occasional monster in the AU: yup, there’s still some monsters lurking around. Plus, college misadventures!), Slow Burn, and Enemies to Rivals to Friends to Lovers.
