Chengwan Lu did not expect that he would actually have a younger brother in his hometown after relying on his mother for a younger brother since he was a child. After longing for his arrival, Wanwan did not enjoy the wonderful life brought by her sister's status. On the contrary, her family status is getting lower and lower, and this younger brother is still meddling with her, and he has a hand in everything she does. But Wanwan is still a little afraid of this younger brother...
Lu Chengyuan, I'm your sister, you'd better be nice to me and do your duty as a younger brother!
Oh? Elder sister? Then I'll be nice to you, then sister can't like other people either.
You! You madman!
Yes, Wanwan, after seeing you, I am no longer myself. I've gone crazy. Wanwan, we still have a long time. I'll spend it slowly with you.
This is the story of a little fairy that everyone loves and her paranoid big-tailed wolf brother.
