Help with designing my second living room

I have an extra room in my apartment I don’t really know what to do with. We already have a room with a wraparound couch and tv directly next to this room and a dining room on the other side.

Any ideas how to utilize this space better? Happy to receive suggestions out of the ordinary too.

PS don’t make fun of my mini tv :) it’s attached to a non-working radiator and we like to stream a fake fireplace to make it cozy!

Thanks in advance!
