Reborn as the Frail Prince’s Runaway Consort

One is the beloved legitimate daughter of the Prime Minister's household; the other is a prince everyone has forgotten. Reborn, Su Yueli vows that in this life she will never become Crown Princess. If her half-sister wants the position so badly, she can have it. All Su Yueli wants is freedom and a happy life. Huh? Since when was there such an ethereal-looking man? It might be nice to bring him home and keep him there. Then she'll ask the Emperor for an edict and claim him for herself.
