Quick Transmigration: The Supporting Actress Charms Them All

She was a veteran employee of the Space-Time Bureau, diligently completing countless missions until she was finally promoted to the supporting female character department. A supporting female character's job was to make life difficult for the heroine, sow discord between the male and female leads, fan the flames, and scheme endlessly to steal the male lead, no matter what her identity might be. So she went right ahead and stole the men. If the heroine lost, perhaps she could qualify for a promotion to heroine. After all, a heroine's benefits were on a completely different level from a supporting character's. For the sake of a bright future and financial rewards, she stopped at nothing (and worked hard). In every world, she stole the male lead, whether he was gentle and devoted, cold and distant, or... any other type. The original heroine could only hide in a corner and cry. He was the gentle, powerful, and unwaveringly devoted Demon Emperor. In his previous life, he had died at her (the original host's) hands. In this life, he had awakened because of her, yet he couldn't bring himself to hurt her. He said that true love was worth starting over for. He was the noble, aloof, and proud True Dragon, destined to sacrifice himself to save all living beings. To save him, she began an endless cycle of rebirth. Seeing her covered in wounds broke his heart, and he swore never to let go of her hand. He... He... She loved with all her heart, never gave up, and kept fighting, all for the most ordinary hope of a promotion and a raise. But what she hadn't expected was that after completing her mission, she would see him again. The tables turned, and he began an unrelenting pursuit, chasing her and refusing to let her go. With nowhere left to run, she looked up at the sky and sighed. All she wanted was a promotion and a raise. Why had her target come to the real world...?
