[From chapter 11 onward in English] - Yoojoon is a good boy. That's why he was destined to fall head-over-heels for the handsome and charismatic Jiho. When Jiho says "Jump," Yoojoon asks "How high?" And as the pair become more inseparable by the day, they solidify their master-dog dynamic. But little do they know, each boy is harboring his own dark secret. Jiho, who suffers from severe apathy resulting from childhood trauma, is using Yoojoon as an expendable toy, and Yoojoon is intensely and obsessively in love with Jiho. Despite that, can the two boys successfully remove each other's masks and break the cycle of abuse?
