Why did Jiusi Gu let Liu Yuru have fingers?

Let her hold her fingers to strengthen her feelings,

Jiusi Gu's love made Liu Yuru understand that a person lives not to marry a good husband, but to be himself. In Jiusi Gu's love, she is no longer a good family living in the inner city. She is independent and brave, and dares to do what she wants. She dared to travel thousands of miles to run a business and gave strong support to Jiusi Gu when she was in trouble. And Liu Yuru's love, on the difficult and dark road of Jiusi Gu's growth from a wan ku to a power minister in troubled times, gave him a little light forever. Jiusi Gu insisted on his moral outlook in hard choices again and again, and was still willing to face life with a childlike innocence after suffering. Therefore, Liu Yuru changed Jiusi Gu.
