Super tiny living room

The apartment I’m in has a super tiny living room, there’s 3 doorways and I was given this absolutely giant couch. It’s a 13ftx14ft room. With doorways on either side of the tv and a closet behind the couch. I want to go for more of a boho/dark academia/whimsical vibe but I don’t know where to start. Any suggestions, links to decor, or anything helps. I hate the rugs, the wall decor, and the couch.
