[Serialized on the 3rd, 13th, and 23rd of every month] [A chest I truly want to have] Jaekyung falls in love with her first love, Kang-woo, whose physique—right down to his chest—is completely to her taste. Then, the most dangerous variable appears before her. It's Taewan, the senior who lives right next door. Closing the distance at all hours, he keeps shaking Jaekyung's heart, and eventually, dangerous desires toward his body begin to sprout. The chest of the man she likes, or the chest of the man she keeps staring at? Jaekyung's precarious campus romance where her body reacts before her reason.
