“monarch of entropy” introduces a cosmic entity of immense power, whose eternal existence was once defined by passive observation. Everything changes when a surprising connection ignites a spark of curiosity and a yearning for interaction. As this King explores his evolving desires, his colossal abilities begin to influence realities on an unimaginable scale. This is the story of a powerful ruler's journey from detached observer to active participant, where every decision, no matter how small or whimsical, creates ripple effects across the multiverse, leading to a series of grand, and sometimes inconvenient, adventures.

To add the needed lustre to storylines and this world. Only, it’s a pity that someone who is not afraid of god-like enemies will be afraid of pig-like teammates.

Bitterly, he realises that for some unfathomable reason, he is being bothered time and again by a bastard who refuses to follow the script… In order to walk the path of a good supporting male lead, he engages in a battle of wits and courage with that person. Loving each other and killing each other, one ultimately cannot escape fate’s teasing– why is it so difficult wanting to be a responsible and diligent supporting male lead?! QAQ
