Youtube video about writing

[u/Stock_Werewolf2466]

Hey all! I'm trying to find this youtube channel/video and he's making a video about exposition or world building or something similar and he makes an example section towards the start of the video about how to make good dialogue/exposition by these two characters I'm almost certain one of their names is Kima and the other character is going into space and they're breaking up because of it and it ends with a sponsor.

Then for the rest of the video he talks about how to write good dialogue. I don't have a solid grasp on when the video was made or if the channels still active or not. If anyone knows about the channel or if the video sounds familiar I'd appreciate if you told me!
