It is the classic DPC foreshadowing more than anything the characters say outright.
-MC's two separate internal monologues upon viewing Jill/Josy
-Entries in the bios about the growing friendship
-Entries in the episode recaps where only key plot points are listed
And why do all of this for just a normal, ho-hum friendship that won't have any effect on MC's story? Lots of people are friends at B&R. Few are worthy enough to be included in the recaps and monologues. There are no coincidences when you are writing a story.
I think it all comes down your MC's chosen LI(s) and what happens between Maya and Josy (and MC) in the next couple of episodes. Josy may want to vent with someone other than MC, especially if MC plays a part in any throuple strife. The only reason DPC put sexually repressed Jill and bisexual Josy (two LIs funnily enough) together is to create more drama. I'm not saying they will end up a couple, but DPC definitely has something in mind with these two. Just accept it and don't fucking ruin
