Han Ke La Ma Bing Xin (韓克拉瑪‧冰心), shortened Bing Xin (冰心), was Han's "twin sister". They were originally the same person, but were divided in two by one of Xia Tian's paternal grandfather's experiments to make a conspiracy; which made them identical twins. She was also Lan Ling Wang's fiancée and eventually wife.
