What attracted blandford to hollis after reading of human bondage?

It seems you're asking about the characters Blandford and Hollis from Somerset Maugham's novel *Of Human Bondage*. However, there is no mention of any attraction between these two characters in the novel.

Blandford, a medical student, is a close friend of Philip Carey, the protagonist of the story. Hollis, on the other hand, is a woman Philip is deeply infatuated with, but she ultimately rejects him and eventually marries Blandford.

Philip is attracted to Hollis due to her beauty, intelligence, and social status. He desires her intensely, despite her cold and manipulative nature.

While Blandford is aware of Philip's feelings for Hollis, he doesn't seem to share them. He treats her with respect and affection, and they ultimately marry.
