Ahhhhh
The domineering Lingchen sect disciple has a relationship with his junior sister
Haha
Although she is very domineering, she only shows her weak side to her junior sister. Junior sister is her preference, and her only one is her life.
(Girls are always weak)
(Oh, by the way, this book is greatly "married" to Y Taeyeon. After reading my book, you can read her "The Emperor")
Purpose: revenge, pure love
