YOUTUBE CHANNEL FOUND!
In my stalking of more trailers and more caps of the ending on youtube, I actually found a Youtube channel with a lot of deleted scenes from Lady and the Liar right here.
I find that a lot of these infringe on copyright (the first few times I tried to link a youtube channel, they got deleted so quickly), so if the channel is removed before you find it, my apologies! Here, they actually have scenes on how Jie Wen and Jiang Xin met and fell in love (which I questioned before), and why Uncle Bai was so impressed with Jiang Xin and even called her brave! Turns out that there was a whole hostage scene that was cut out. That explains so much more! A lot of the deleted scenes actually really helped justify the plot and the dialogue more.
Sigh I am so tired of c-dramas cutting things out because it makes things so confusing! I don’t mind having more episodes – they air more than one episode per day anyways.
