The Entire Interstellar World Is Waiting for the Little Highness to Choose a Consort

(The novel's title has nothing to do with this story, and there are no livestream elements. I can't change it.) The Luo family, an interstellar tycoon dynasty, is throwing a third birthday party this year for their youngest son, Luo Yunci, the apple of the whole family's eye. At the party, he meets the Empire's Crown Prince, Yun Jing. Luo Yunci sweetly calls him “Big Brother,” and the story begins. Hope you all enjoy Jing and Ci!
