My parents divorced ten years ago, and I secretly returned to China to seek refuge with my biological older brother, only to mistake Lu Peize, my mortal enemy from the physics department who shares the same name, for him. Every day, I clung to him, acting cute and demanding bedtime stories, bossing him around as if I owned him, maxing out his black card, and transforming his cold, empty mansion into a girlish wonderland. It wasn't until I ran into my real brother that I realized the truth in the most mortifying way possible. I packed my bags and fled in the middle of the night, trembling as I sent him a tentative message: "Does no longer relying on my brother mean I've grown up?" He replied instantly: "It means cheating." As it turned out, he had known the truth all along. He simply wanted to keep the only light that had ever entered his desolate world.
