You must have too much of an imagination... . In most wuxia type of story, the sexual situation or encounter is a catlyst to form new story arcs... Eg a misunderstanding or a reason for revenge.. or an innocent intimate moment to build their relationship. Not for entertainment's sake... We're just talking about the fate of the nun... I seemed to have recalled some of those scenes in older remakes... They were innocent encounters... It's just a sene idea... I never mentioned sex scenes, you can watch those anywhere on the net if you prefer. A misunderstood sexual encounter or making someone happy just before her demise is very common in wuxia stories...
