Lethal Allure

Summary

Ever since my brother found out I wasn't his biological sister, he's been treating me like I’m made of ice.

The heartbreak was unbearable.

As I was packing my bags to get out of his life, I stumbled upon his journal.

【I’m so screwed. She’s not my real sister. I can’t control myself anymore.】

【God, I want to kiss my sister's... her.】

【She crawled into my bed tonight, her face flushed from the heat, whispering 'brother' in that soft, sleepy voice. It almost sent me over the edge.】

【She can’t even solve a simple calculus problem. It drives me insane. Makes me want to take a whip to her.】
