Transmigrated as a Rich Young Master, Stolen by His Sister's Fiancé

Kim Taehyung never thought his dull, routine life as a 29-year-old office worker would end in something as absurd as waking up in another universe. But that's exactly what happened. One morning, he opens his eyes not in his cramped apartment, but inside the body of a wealthy young man-still Kim Taehyung, still his face, only five years younger, and with a background he can barely wrap his head around.

Here, he isn't a weary salaryman but the spoiled son of an influential family, the type of man who burns money like it's paper and lives off the whims of a powerful father. To make matters stranger, a mysterious system keeps guiding him, instructing him to do pointless tasks-mostly encouraging him to squander wealth in increasingly ridiculous ways.

But money is the least of Taehyung's problems.

Because soon he realizes his new identity comes with complicated ties: a younger sister engaged to one of the most infamous chaebols in the country. Jeon Jungkook-wealthy, youngest, untouchable, and wrapped in scandals that follow him like shadows. He's notorious, arrogant, the kind of man everyone warns you about.

Yet for some inexplicable reason, Jungkook's attention veers away from Taehyung's sister-and onto him.

And the worst part?
Taehyung can't even deny what's already happened.

He's slept with Jeon Jungkook.

Now, in a world that isn't his, bound by a role he never chose, Taehyung finds himself caught between the absurd instructions of his system, the dangerous charm of his sister's fiancé, and a life that feels borrowed. The more he tries to escape, the deeper Jungkook seems to pull him in-and the line between survival and desire begins to blur.
