If you are a curious soul and are just "dying" to know what the bloody letter says, I provided the English translation below. :P Enjoy the short read!
"Don't send anyone to come find me. The world is boundless, you won't be able to find any trace of me. Ah Zhan, don't grieve because of me. In my heart, you have always been my husband. I'm sorry. Goodbye, and I love you. Ah Zhen"
Now, this letter really got me thinking whether Lu Zhen and Gao Zhan officially tied the marriage knot...at least in private. According to BTS photos I previously posted, they shot a wedding ceremony, but I have a feeling that "wedding" scene may just be a dream sequence. Every summary I read and the trailer seem to imply they never officially "married." Also, the trailer also seems to imply that Lu Zhen became sterile. Hence, Gao Zhan's sister's extreme disproval of their union. I hope I'm just reading too much into things and all the bad things I'm speculating will not come true! I'm already dying to know what happened.
