When She Stole My Lover

Watched it because Jin Zhu-xing is in it, and turns out it's based on the Chinese short 'Crossed Fates.' I already knew the story, but Jin Zhu-xing serving up his regret-guy, obsessive-guy, psycho act means I've gotta watch. What's different from the original is the cat-and-human? mistaken-for-a-sibling thing. You already hurt me every way possible and think a 'sorry' fixes it?
