Wasn’t I the Protagonist of a Regret Novel?

A single, curt word slipped from her husband’s lips. “I’ll agree to the divorce.” Vendia Rose dropped the divorce papers she had just handed him. “T-This isn’t how it was supposed to go…!” Vendia believed she had been transported into a regret novel, where asking for a divorce would mark the beginning of her romance with the male lead. But contrary to her expectations, the divorce was finalized almost immediately, and she ended up living in an old mansion she had received as alimony. “All right. I’ll take this opportunity to live the dream as a wealthy landlady!” But how long had it been since she made that bold declaration? “When are you going to fix the fireplace?!” A troublesome tenant demanding a working fireplace in the middle of summer. “M-My lady… should I bury him?” A manager whose suspicious way of thinking did not match his innocent appearance. “It has been a long time, my wife.” And even her ex-husband, who had accepted the divorce without hesitation, had appeared.
