Before you knew

You're roommate has moved away with her boyfriend. After some time you decide to put up another add, needing someone to share the rent with. Clay messages you, and you two start to text about details. Soon he comes over to take a look and you two click, so a moth later he's settled in, but....

'I'll be working in my room.' You nod at him before he turns and goes upstairs. You get a notification from sapnap who is starting a stream, so you go and watch, seeing how Nick is a friend of yours.

During the stream you hear yelling that adds up with that of your roommate.
Can it be?
