Until one night, a fairy empress in the fairy world was poisoned by the love poison and fell into the mortal world and landed in his room...
That night, by mistake, the clouds turned and the rain fell, the dragons and the phoenixes cried...
Afterwards, the empress left quietly. I thought it was just a spring dream without a trace, but I didn't expect that ten years later, she came to him again, and brought a child who claimed to be his daughter! ! !
Ask him to take responsibility!
"She is your daughter, you have to be responsible for me and her!"
