I just found a bit of time to watch this.

In my interpretation Kyomoto represents art for the sake of art. Where she can’t really function in the society as it isn’t profitable to do. Fujino on the other hand draws for money and clout. As she said “It’s not fun, just plain tedious and super unglamours too.” But without Kyomoto, Fuijino won’t go anywhere as a mangaka. She needs someone to move her. She needs to have a reason. And that reason becomes Kyomoto.

Surly I have skipped some details that contradict my interpretation but for me it’s good enough.
