This book has absolutely nothing to do with pear blossoms. The heroine's name simply comes from the poem "Pear Blossoms at Lingxu Palace" in No Worldly Thoughts.
Zhuo Luo, the heroine of this book, has a mysterious background. Heroines usually have mysterious backgrounds, and she is no exception.
He Xichuan is a fool. Male leads usually aren't fools, but they all love the heroine foolishly, so they're all fools in a way.
Waiting for the truth about the silly male protagonist~
