She wanted to see Evander, but he didn't bother to check on her. Instead, he went to meet that white lotus.Unable to bear the betrayal, she decided to free Evander from this marriage, leaving behind a letter and divorce papers, claiming she now had someone else she loved!~~~~“You’re mine, and I’ll never let you go!” he declared, his voice dark with possessiveness.“But I don’t want you anymore! You can have Susan—I’m now in love with someone else!” Claire shot back, her words sharp and final.“You can't be with anyone. Do you even know how sleepless nights I've without you?” Evander's hold on her tightened. “I'll see how you become some else when I'll claim you,” he pronounced before crashing his lips on her.

In modern society, a 24-year-old ordinary young man Reid managed to avoid a dump truck and declined the invitation to the reincarnation space, only to be sent to the Marvel Universe by a computer malfunction. There, he obtained the DC role-playing system. As a result, the Marvel Universe got a taste of the darkness from the DC Universe.In order to protect the Wayne Corporation, Alfred pulled the trigger on the executives supporting the IPO.To eliminate the mutant threat, he allowed Jean Grey to be infected with the Joker infection.Captain Marvel, who served as the cosmic police, could never have imagined that the Martian Manhunter, who followed her in fighting against the Kree empire, had been secretly controlling her mind all along.“I am indeed playing the role of a hero,” Reid did not deny this. “However, it's a hero that belongs to me.”When the threat was finally neutralized and the Justice League ascended the podium, people realized they had already been shrouded in injustice.
