i read a fic from another fandom but i thought it would suit sukufushi too but basically it was about (let me change the names to skfs) megumi getting dumped by his fuck buddy/best friend. heartbroken, he went to a bar and got drunk. the bartender (sukuna) tells him he needs to go when it's time for the bar to close. the thing is sukuna has been eyeing megumi ever since megumi and his ex-bff started frequenting that bar. sukuna ends up taking megumi home and fucking the heartbreak out of him. they start meeting for sex and megumi develops feelings for sukuna but sukuna strictly doesn't date his flings. still, megumi falls anyway, and being the rich brat that megumi is, he throws a tantrum about sukuna taking responsibility for his feelings and sukuna is like fuck it fine you brats always have to get what you want. sukuna in turn warns megumi that once they date, megumi is going nowhere because sukuna is going to hunt him down if he runs away. the end
