下面是一段名为“Lonely Nights”的短篇小说。
I look up at the sky again, the same one I have been looking at every night since you left. I indulge in misery, the memory of you wraps around me and suffocates me. Your absence fills me with a void that I cannot bear. This loneliness, it's unbearable. I try to distract myself with work, with friends, but nothing works. I don't want to pretend I'm okay anymore. I need you back in my life, without you, everything feels empty. It's been months since we broke up, and every day feels like an eternity without you. Maybe, just maybe, one day you'll realize how much I need you and come back.
