Nangong Wenxue lost her memory, but her older brother, Nangong Jin, told her she'd been found and taken in. Nangong Wenxue believed him without question.
A few years later, Nangong Wenxue found herself a little sister, too.
But why were her brother and little sister looking at her more and more strangely?
After arriving in the cultivation world, her master told Nangong Wenxue that she hadn't liked her before. Nangong Wenxue nodded. If she hadn't liked her, so what? What did it have to do with her?
Wait, you said you didn't like me before. What about now, Master?
What do you mean, I smiled politely at a fellow disciple and he fell in love with me at first sight?
Junior Sister, I only gave you some pastries I made. I didn't bind myself to you!
Nangong Wenxue glanced around and found a tsundere little bird by her side, too. What a wonderful life!
Sigh, I only did what I was supposed to. How did you all end up falling for me?
(No CP basically means you can ship whoever you want. Family, friendship, romance, anything goes; no pressure.)
