no it hasn't been asked! but im glad someone finally did. even though i dont have many of my own hcs about them im still an arlefuri sister and a furina plushie owner, so i think i should at least give a few <3

1. after the events of the archon quest&furinas story quest arlecchino likes to come and watch some plays where furina is performing
2. i imagine arle is super into furinas singing, like maybe after a long day she'll lay in bed next to furina and quietly ask her to sing to her
3. this is based solely on a few arlefuri comics ive seen but i think furinas little pet guys just. DO NOT. like arlecchino. not even because she attacked furina, they just dont like her. imagine a cat who doesnt like visitors and hisses at them, thats basically furinas salon members
4. i think arlecchino would want to enter back into furinas life somehow, but shes not quite sure how to do it after the whole archon quest shenanigans, so she tries reading books about how to communicate and be nice ... freminet probably finds it and questions her about it, and i think she would try to deny the fact that those even belong to her
5. i think arle and furinas tastes in food are really different... id imagine arlecchino really doesn't like macaroni for what ever reason, and it gets furina frustrated because... thats literally all she eats. arle tries to tell her that its okay and that she doesnt need to make her a separate dinner and that she can do it herself, but furina INSISTS upon giving her wife some dinner too, especially after a long day..... they bicker about that often
