She dressed as Bai Yueguang's stand-in for the villain boss. She thought she was just an extra, but she didn't expect that this man who was rumored to be paranoid and cruel would be gentle and gentle to her. In front of outsiders, he was a feared business overlord, but in front of her, he was willing to wash his hands and make soup for her. When Bai Yueguang suddenly returned, she was about to leave the show gracefully, but the man who had always been calm and self-possessed pushed her against the wall with red eyes and begged her in a hoarse voice not to leave. It turned out that he had already given her his sincerity as early as those days when she was trying hard to act as a substitute. This is a game about a substitute and true love, and it is also a heart-warming story about redemption and growth. When the gears of fate turned again, she realized that she was no longer someone's substitute, but the only Bai Yueguang in his heart.
