I first thought it's about yeon and ji a love story only but it's also about rang and yeon brother love i did't expected rang will give his life i think he is my favorite in this drama in 15,16 episodes i can't stop crying because yeon and rang when yeon give up his life for ji a. Rang can't taked it because he have to stab his brother who he love more than anyone in episode 15 rang become a heartbroken person but when yuri married he slowly becoming ok but when rang and ji a met afterlife judge first ji a said she give up but instead of ji a . Rang give up his life for yeon my most painful moment is when rang said goodbye to his family i thinked after yeon cameback yeon will find the way to bring rang back but rang did't cameback it is most sad moment it's be a full happy ending when rang also cameback but it not happen but it is my favorite drama because yeon and rang brother relationship in all story only lovers give sacrifice but in this drama rang give sacrifice to bring his brother back i really liked this drama
