Happy Life System (EnglishVer.)

"To get something, you must lose something of equal value."

This is a golden rule that should never be broken to maintain world balance.

But a cursed element, created by a very powerful devil, breaks the rule and creates chaos in all the worlds. This element is: the protagonist halo.

'The halo' is an object that takes the good fortune of people in the world and transfers it to its carrier, leaving only bad luck and breaking the golden rule. The halo causes those who deserve the fortune to be miserable and the sinners fortunate.

Mu Yun is one of these unfortunates. He had the misfortune of having as a younger sister an ungrateful protagonist, carrier of the halo. All his life he suffered bad luck and died at 19 years of age, being cruelly murdered by the male protagonist of the world.

With a little resentment in his heart he found himself in a dark space lit only by a white ball in front of him. The white ball was called a 'system' created to destroy the protagonist halo and return the worlds to normality. And he, Mu Yun, was chosen as his host.
