Busy female looking for room

I am a full-time student in an accelerated bachelor's program working remotely. I like to keep to myself between work and school, and I'm pretty introverted. I have a senior 13lb Chihuahua mix, which is incredibly well-behaved, super quiet, and sleeps a lot. I keep her with me or in the room with the door closed. I don't smoke/drink. I rarely have anyone over, and even then, only in my room, not the shared spaces. I'm not looking for any girlfriend arrangements, FWB, etc.
