If you are a fan of Kim Ki-duk, you'll find this film very interesting. Kim, in many of his works, seems to stress that spiritual or Platonic love is more precious and valuable than physical love. Some may find his films odd and hard to accept, but once you get used to it and accept his philosophy, you'll love him. I myself am a good example. Kim Ki-duk is undoubtedly one of the most important film directors in the world today. Take my advice, keep tracking him, he won't disappoint you.
