Stealing became the middle names of Momo, Sana and Mina. After their parents died in Japan, they were sent to the Twice Orphanage in Korea but it’s not like what they’ve imagined. Now, they’ve been given a mission to steal the heart diamond in the Royal family’s mansion but it seems like their hearts are the ones that’s been stolen.  ForewordThis is my first fanfic in this fandom so please be easy on me. English is not my first language so I’m sorry about the grammar and spelling errors. Just read and enjoy~
