Evelyn Grimes lives in central London, around all the shops and places, and lives a pretty normal life. Except for the fact that she is severely depressed, and suffers bulimia, and cannot find a way to stop herself from thinking about, and also considering suicide. Her friends are very concerned with her behavior, so they try to lift her spirits by taking her out to parties. One clear, starry night in London, Evelyn's friends decide to take her to a party at a local club, a favorite of theirs. She is reluctant to go, but comes along anyway, hoping to stop their constant intrusions to her life. Alone in the bar, Evelyn fights the misery inside her, when a young, handsome man comes and sits next to her. He seems a bit intoxicated, but like a gentleman, he formally introduces himself to Evelyn as Daniel (or Dan) Howell.
Dan Howell is an insomniac....who's scared of the dark. Only a little bit. One late night (or early morning), he decides to venture out and explore London at its quietest. He meets Phil Lester at an all-night coffee shop, and the two quickly become friends. As the friendship continues to grow, Dan has to begin facing his issues, and his feelings for Phil.
