<human>: Could you distill the essence of the text into 1-3 sentences?

Ok, me and my roommate of a year share a studio together. It's not a small room, per say, but its an open space with 1 shower and 1 bathroom. I can see everything she does and she can see everything I do. I don't really mind this arrangement because rent is hella cheap for the location. 

My roommate is an international student. I'm not really friends with my roommate. we mostly ignore each other's existence. both of our name is on the lease tho. 

Now, I don't mind if she has friends over once in a while. hell, I have friends over once in a while. But its important to me that her existence does not bother me. 

Yesterday she told me that her tribe members (she belongs to an African tribe) are coming to stay with her. But the thing is, she refuses to tell me how many, (with implication that there's more than 2), what are the sexes (I don't wanna room with a guy), and for how long (with an implication that until the lease is up). All she said is that they have no other choice but to stay with her because ?? reason. She was being super vague about it, but it looked like she's about to cry because she accepts homelessness for them.

We already live in a small room, with one bathroom. 
I barely manage to share the space with one person, I cant imagine having more people in our room. I want to have fucking privacy and piece of quite for fucks sake. I didn't pay to have a questionable amount of roommates. 
I don't really know what to do. I don't think the landlord cares too much. She expects me to let her turn the room into a homeless shelter.
<bot>: Roommate who I have no relationship with wants me to house her friends for indefinite amount of time. I'm firmly against it but I also have no say in the matter.
