Intro

High-school Minho and his sister could easily pass as twins even though Minho is 2 years older. They have a brilliant brain and special memory that helps them remember every detail even after hearing or seeing something at least once. Their mafia dad quickly learned about this ability of theirs and trained them as weapons all through their childhood.

Their life starts to get real complicated when they are forced to move back home to Seoul and Minho starts to fall in love with an old childhood friend, Han Jisung, and his sister starts to fall for Bang Chan. The two mafia siblings risk everything to try and keep Han and Chan safe.
