Shen Xingyao, the beloved daughter of the Shen family, chooses to become a journalist instead of inheriting the family business. Li Chenlan, the eldest son of the Li family, voluntarily gives up his inheritance rights to pursue his dream of working in aerospace. By an unexpected twist of fate, the two end up married through an arranged marriage between their families. Shen Xingyao initially assumes that after marriage, they will each go their own way and stay out of each other's lives. To her surprise, however, Li Chenlan dotes on her endlessly. It is only later that Shen Xingyao discovers that Li Chenlan has been in love with her for many years, and that everything was part of his carefully laid plans. As it turns out, ever since childhood, a star named Shen Xingyao had illuminated Li Chenlan's life and guided him toward his aerospace dream. In Li Chenlan's eyes, Shen Xingyao is his entire universe, his starry sea.
