ino and naruto used to date but they still good homies. ino helped naruto date sasuke so yeah, they havent talked in a few years after they started college. but then naruto and sasuke were kicked out of their home because they couldnt really pay for everything.
and then naruto looks through his phone and that one contact says "the bae *iphone emojis*". and he shows sasuke (gets angry that is says bae but he explains in a platonic way) and then they like CALL HER.
naruto is hella nervous because they havent seen each other in a while but she picks up like "who tf is this" and naruto gulps and hes like "your ex, naruto". then everything gets all "OMG THE BAE HEY!!! I MISSED YOU" blah blah then he explains they need a place to stay at and shes cool with it.
ino lays down the law that they must get jobs that can help buy groceries, pay the bill, and do some of the chores and they agree. shes the most dominant in the house since its hers lol. so they all become buds w/ sasunaru.
