I'm Looking for a Book, It's a Yandere Novel.

I remember that one of the female protagonists is a painter and thinks that the male protagonist is a work of art. On the one hand, there is another yandere, and there is another game anchor. He had a conflict with his family and ran to the park. He was taken in by the male protagonist. He is a dependent yandere. I forgot what the book is. Does anyone know?
