What metaphors does o'brien use to describe his love for linda?

I believe the correct answer is that he wants to melt into her bones.

In is a collection of linked short stories "The Things They Carried" by American novelist Tim O'Brien, the metaphor he uses to describe his love for Linda when he was nine years old is that he wants to melt into her bones, which means that he wants to be with her all his life and he hopes that they will reunite again.
