Used up all effort for nothing

Lanni took a moment to process what Luna had just said and frowned. How could Luna say such words? "You do know that she is our mother, right?" 

"Yes. Which is why I didn't want to point this out before. I didn't want to create friction between you two." 

Lanni still found it unbelievable. Although she knew that her mother made some ruthless decisions sometimes, it was all with a good reason. "What made you think that way of her?" She asked gently. 

"Can we not talk about it anymore?" Luna knew what her sister wanted. She was probably trying to understand both sides so she would come up with a solution that would make she and Li Yuming understand each other more. But the problem was that between her and Li Yuming, there was really no solution unless time could be reversed. 

Lanni sighed and stood up. "If you ever want to talk about it, you know where to find me."
