When Earth's entire population is forced into a universal survival game against alien races, Ren, a timid and honest orphan who starts with nothing due to a registration error, discovers a broken multiplication ability when gifting resources: a base multiplier scaling strictly with his level (Level 1: x10, Level 2: x20, Level 3: x30...) while intimate partner bonds unlock qualitative systemic upgrades - multiplying stat points for Ren and his partners, duplicating unique items, and granting access permits to dungeons and special zones. Partnering with Veyra, a clever alien novice who decodes the formula, they exploit the game to live in supreme luxury, cause playful economic chaos, and expand Ren's circle of bonded lovers to turn the death game into their personal playground.
