Answer:
The line "with torn and bleeding hearts we smile" develops the speaker's point of view by contrasting the speaker's true feelings with their outer appearance. The phrase "torn and bleeding hearts" suggests that the speaker is experiencing strong emotions, possibly pain or sadness, while the word "smile" suggests that the speaker is presenting a different, more positive appearance to the outside world. This contrast suggests that the speaker is hiding their true feelings and putting on a facade in order to cope with difficult circumstances.
