what is more worst? Someone who you didnt love cheated on you? or someone who you really love and loves you back so much but in order to be happy she needs to keep a little lie?

it may be little....... but it is deadly.

As Bae Seulgi work as a merciless right hand killer who works with the most wanted mafia king in Seoul, who fell in love with her sweet and charming childhood bestfriend named Park Jimin who doesn't know she works for the most wanted man,

They loved each other, but..... what if Jimin founds out her little deadly secret? will he still loves her since she was CAUGHT IN A LIE?
