"Also, didn't you say this was your birthday gift from Father? But look at the auction date on the receipt! That's my birthday! My first birthday! Why would Father buy this crown from an auction on my birthday and give it to you for your birthday afterwards?! Gu Yanran, you are a complete idiot, but do you think the rest of the world is as stupid as you?!" Gu Nianzhi blurted it out in one breath and was so angry, she panted slightly.
She could only be thankful that Father had also requested that the auction house keep his request for engraving confidential all those years ago. So even though Gu Yanran got her hands on the Christie's auction receipt and purchase record as evidence, she didn't know about the engraving at all. Otherwise, Gu Yanran would've never dared to publicly gift the pink diamond crown, even if she was forced at gunpoint.
