[Blurb to be decided, premise unchanged.]
Ning Yunshu was reborn as the female lead's sister in a yuri novel with explicit content.
She also became the younger sister of a yandere in the original story.
And she had a special constitution: whenever her emotions ran too high, she couldn't stop crying.
*
At first, Ji Ning was annoyed whenever she saw Ning Yunshu cry. Later, Ji Ning loved kissing her red eyes and licking away her tears more than anything.
*
Not related by blood, adoptive sisters. A warm little sun with a tendency to cry uncontrollably x a gloomy, possessive yandere.
Theme: They were made for each other.
