>>3874497There are some people that watch Ina but not Kiara (or vise versa). By being the waiting for Ina stream, Kiara is getting a few eyes on her that normally don't watch her. There's the possibility that SOME people may actually like what they see and decide to stick around, leading to an increase for her.
In addition, she's trying to get hashtags going which will bring more eyes on the situation. While most of the people watching are just going to Ina's stream to wait, some are also checking out Kiara's stream as well. So that's also a net positive for her.
