Nangong Su transmigrates, never expecting to become the adopted son of a Clock Tower Lord. A thousand-year-old family with connections everywhere, an adoptive father away on business, and a tsundere stepsister?
"I get it, it's El-Melloi..."
"What do you mean Marisbury is my adoptive father? Can I still make a run for it?"
Just as he's packing his things to flee, he unexpectedly awakens the [History Simulator], and learns that if he completes a simulation, he can inherit the abilities from it and change his circumstances.
"So whether the history I create is orthodox or unofficial, a power fantasy or some unhinged story, pure romance or hardcore stuff, I can inherit it all?"
Nangong Su understands everything. Nangong Su begins simulating!
Spanning thousands of years and passing through the great myths, Nangong Su, who has paid tribute to the legendary King of Lovers, falls into reminiscence:
"They mock your efforts. I'll unleash Ragnarok to teach them a lesson."
"If Britain can be saved, I hope to create a Britain with you in it."
"If the age of prosperity can only endure through your death, then let this fire burn it all away."
"If I cut off all my tails, can I really become your wife in the next life?"
Nangong Su is just about to use some subtle language to greet the System when he looks at his stepsister, who has pinned him to the bed.
"What do you mean you've been waiting for ages, and now you're not waiting anymore?!"
