My Little Secret With the Demon Lord

"Aunt, when I grow up… will you marry me?" No… No way! The kid was already thinking about making her his wife, but she is a minor immortal from the Immortal Yin World. She could not get together with a young human boy, no matter how ordinary she was. Yet, 500 years later, she was sent to congratulate the Yang Demon World’s young lord, Li Ye on his wedding.

To make things worse, he did not recognize her, and was trying to get her killed… Should she tell him the truth and clobber the brat’s handsome and immaculate face? (Source: Bilibili Comics)
