My Crown Prince Can't Possibly Be This Cute

My younger brother is smarter and more handsome than me, and he's secretly plotting to kill me. What should I do? Asking online, and I need an answer fast! My military-minded younger brother has won countless battles. My talented younger brother has been famous throughout the capital since childhood. My cute, clueless younger brother is protected by our parents and wants for nothing. My carefree younger brother roams the world, living a life of freedom and romance. And me? The eldest prince! Average knowledge, average martial arts, average talent, average upbringing. I can play all the refined arts, but I'm an expert at none of them. Yet I'm the legitimate eldest son, with no great achievements or failures, and I've been named crown prince. Now, wherever I go, I can see my younger brothers watching me like tigers eyeing their prey. I, the eldest prince! A good-for-nothing with the role of cannon fodder. In this imperial city, surrounded by danger and enemies on all sides, I'm a fat, juicy human target. I have just one goal: to survive in this messed-up world! Cover art by my friend @He Jihe
