The teacher told the painter not to paint yaoi anymore.
To help the teacher, though, the painter agreed to paint for the master.
The master's boyfriend/plaything is jealous of the painter, that's why he poured water on the painting.
The master thinks the painter sabotaged his own painting because of the painter's promise to the teacher

I am so- so- misunderstanding this story . The owner is jealous of the painter? Need help.
