One person had a failed marriage. He was calm and rational on the surface, but actually sensitive on the inside. He had a slight desire to control and was used to handling everything professionally, including relationships. His ex-wife left because she couldn't stand him putting work before family, and he had a son.
A man in his prime, gentle and well-behaved on the outside, but stubborn and opinionated on the inside; he enters society with idealism, but also has practical wisdom.
He is 42 years old and she is 27 years old. They should be two parallel lines that do not intersect, but they unexpectedly intersect.
