my roommate won’t stop rearranging the sofa

okay so i got this modular sofa from rovelab because it seemed perfect for our small shared apartment. the idea was we could move the pieces around whenever we needed more space or wanted to switch things up. but my roommate has taken it to a whole new level. i come home every day, and it’s in a completely different configuration. one day it’s a sectional, the next day it’s broken up into individual chairs, and yesterday, she made a weird couch fort out of it. i get it, it’s fun to move around, but i’m starting to feel like i live in a furniture maze. is this normal or do i need to set some sofa boundaries lol anyone else with modular furniture deal with this or is my roommate just extra creative
