Nick Carraway from "The Great Gatsby"

Nick Carraway is the narrator of the whole book, so we see everything from his point of view. This gives us a little description of himself, for example, we hardly know what he looks like, but we can get a sense what kind of a person he is, as he introduces us to his ideologies and view on the world.
In Chapter One Nick Carraway tells us about his past and notes that in the college he was "unjustly accused of being a politician", and though he mentions "unjustly" we get a sense that he is good at telling people what they want to hear.
While reading the novel, we can clearly see that he over-romanticises most of the things by giving poetic descriptions and sometimes using words that are quite uncommon, for example, what he says about Daisy that she had a "warm human magic" puts her in a different, almost magical world.
From the novel we get a sense that Nick is actually quite lonely and almost empty. At one point he even imagines that he picks out "romantic women from the crowd" and follows them to their apartment, which seems a bit crazy and even scary, but I think this is what people sometimes do(or imagine doing it) when they are feeling lonely.
His confusion shows in the relationship between Jordan and some other person, whose name isn't mentioned. He couldn't understand what he felt to both of them, as he says, at one moment he thought that he loved Jordan, but later added that it wasn't actually love, he "felt a sort of tender curiosity".
Nick is also a nostalgic person, he reflects on his past few times throughout the novel.
