One Day She Became the King's Daughter, Si Yuyue

Li Qingyue traveled through a comic book and became a three-month-old baby with the same name as him. In a rafting competition, he met the heroine Si Yujin. In the original plot, the dog emperor only accepted Si Yujin as his adopted daughter in that game. Later, he adopted the three adopted daughters Si Yuzhen, Si Yushan, and Si Yumei. But somehow, he adopted the heroine together. What will happen to the story next? (I write it for fun, just write whatever you want, don't comment if you don't like it)
