Between piecing together Hua Mulan’s scattered memories, grappling with her fellow villagers’ prejudice against her, and fending off Mrs Hua’s attempts to match make her, He Mulan has her hands full. All He Mulan wants to do is protect Hua Mulan’s body till her soul comes back, but fate has other plans…
