When Shi Nuan married Song Yansheng, she really did have an agenda. She wanted to make use of Song Yansheng, but she also didn't want to owe him.
She knew this was hypocritical, and Song Yansheng understood this hypocrisy in her, and gave her reasons she couldn't refuse.
She had always been very grateful to Song Yansheng. Even when she had nothing and could do nothing, he still gave her respect to the greatest extent.
She had once thought, if she had known earlier that Song Yansheng married her out of love, would she still have accepted him?
Probably not. Once upon a time she accepted Song Yichuan not because of love, and she had always felt guilty toward him for that. She already owed one person and didn't want to owe another.
Falling in love with Song Yansheng was unexpected, but also inevitable. At that time, she felt she was a lucky person.
