"Love Triangle" 한국어로 I have to give a presentation, and the topic is an introduction of "The Phantom of the Opera." (오페라의 유령). I need to be able to explain the plot briefly, which means I need to know how to say "Love Triangle" in Korean. I've never had to say that or think that in Korean before. Please help me with the term. Also, what would you call the mask that the phantom wears? Is that 탈? or 마스크? or something else? Thank you.
