Why are angels open to novels?

We have worked together before and are good friends in private. According to relevant information, we have cooperated before, so with the foundation of the first cooperation, angels and fiction seem to be more familiar, not only joking with each other, but also the intimate interaction on the set is very natural. They are also good friends in private. They also like to tease each other and joke with each other during interviews, so they are more open when filming.
