After a wild night at the bar, a down-on-his-luck young man finds himself unexpectedly becoming a father, thanks to a cunning beauty. As if his troubles weren't enough, his rented apartment changes hands, and he's on the brink of being thrown out. However, the new landlord is a stunning woman! Should he consider a roommate arrangement with her? When he tentatively suggests it, she dismissively responds with just one word: 'Scram!' This marks the beginning of a complicated emotional entanglement, all stemming from a housing dilemma.

Your translation is quite good, but I've made a few adjustments for clarity and flow: Gao Yang, an orphan, traversed to a "Parallel World" at the age of six and has been living in a warm family of five ever since. At eighteen, Gao Yang accidentally unravels the truth about this world: it's not a parallel dimension, but a mysterious realm where everyone around him, family and friends alike, are dreadful "beasts"! Upon discovering this truth, Gao Yang narrowly escapes death, crucially gaining the [Luck] system—a power that grows the longer he survives. Thus begins a deadly game between the lamb and the wolf.
