Trapped in a Webnovel as a Good-for-Nothing

Synopsis

After a long night of overtime, an ordinary office worker falls asleep and wakes up to find himself inhabiting the body of a despised, tantrum-prone villain in a webnovel. This character, born into the wealthy Haesung Group conglomerate, is destined to be manipulated and killed. Realizing he must change his fate, the new occupant of this body seeks ways to survive. He aims to convince others to support him, become strong enough to protect himself, and avoid antagonizing the powerful 'Returnee Master.' However, even before he took over, the original owner had already caused a significant incident. Faced with the impending threat of a Demon King, he must navigate the complexities of this world to survive and alter his predetermined destiny.
