Karl, a young man stuck in a rough patch after losing his job and burning through almost all his savings, wandered through the cold, dark streets of Eldoria. On the damp, silent sidewalks, he stumbled upon something bizarre: an old gacha machine mysteriously appearing at every corner he turned, almost as if it was following him. Driven by a mix of curiosity and the overwhelming weirdness of the situation, Karl finally gave in and used his last bit of money on the machine. From the gacha ball, he pulled out a card with a barcode.Back in his cramped apartment, curiosity finally won over caution, and Karl scanned the barcode. To his shock, an app called “Common Sense Manipulation App” installed itself on his phone, claiming it could alter people's “common sense.”------Support Me By Gifts or Power Stones-----
