White Nights by Fyodor Dostoevsky:

White Nights is a short story by Fyodor Dostoevsky that was published in 1848. Set in St. Petersburg, it is the story of a young man fighting his inner restlessness. A light and tender narrative, it delves into the torment and guilt of unrequited love. Both protagonists suffer from a deep sense of alienation that initially brings them together. A blend of romanticism and realism, the story appeals gently to the senses and feelings.
