They all thought I was just a rogue soldier who had crawled back from the border, covered in gunpowder and looking for revenge for my family's old debts.
Everyone was guessing which building I would blow up next. Julian, as I expected, panicked.
He recalled all his elite personnel to the Vientiane Building, activated top-level security, practically turning the entire office building into an impenetrable fortress, and sealed off assets globally to prevent my "illegal theft."
But he made a mistake.
When he personally pressed the reset lock, attempting to regain control of the system through manual verification, he didn't hear the prompt of command execution, but rather the hydraulic hum emanating from the building's load-bearing walls—it was the "self-destruct program" he had personally signed, running as scheduled under the guise of my privileges.

As a leader, it turns out there are still things we cannot control. First, fate, and second, arranged marriage by parents. Reinhardt must marry Leonard, who is the leader of another region, to expand their territory and fulfill their parents' promise.
However, Leonard turned out to have an illicit relationship with Veronica, a friend, a confidant, who was as close as a heartbeat. Betrayal forced Reinhardt to eliminate the people around her, soothe her heartache and resentment, and heal her disbelief in someone once again. Then a man with a secret identity named Jean arrived in Reinhardt's life to become the solution.
