i was kind of hoping to brainstorm a bit since i know relationship lines are so character dependent but i was kind of hoping her ex was a bit more settled and responsible than she is? holly isn't immature, exactly but she's slightly stretched thin trying to do her comedy stuff and her day job and her ex was sort of a bit um, pick one and go all in? your life's kind of chaotic. and with her nights being so busy trying to do open mic nights and the like i feel like that could have put a damper on things as well as all her free time goes to her comedy stuff, she's out late, etc. they can be sort of begrudgingly getting along and better off as friends or hostile and/or awkward as you like. i just think it'd be a fun and interesting non traditional roomie dynamic.
