I have just read the alternative ending with English translation found on Google. May contain spoiler if video is ever made of this ending. It seems Yu did not die in the accident (just Xiang having endless nightmares about this) but suffered serious injuries instead. Fast forward four years to when Xiang and Yu graduate from unil. After, Xiang fulfilled his promise to Yu and took him up Jade mountain on the first step in Yu's quest to finally see his deceased parents. While on this trip Xiang proposed to Yu with two rings, one for each of them. At the end Yu told Xiang he would choose their wedding rings once they had reached the Himalayas summit (in another 2 years after Yu had completed his further studies) where he would finally see his deceased parents and for them to meet Xiang, his future husband. Some contrast to the original ending. Why not this happy ending in the original version? Excited if a happy ending video can become a reality.
