Yasu is hired to kill people on a routine basis. He does so by getting close to the people in question, or those around them. He forms friendships, and cries with the rest at the sudden deaths of his so called friends... but what if things went too far? What if the assassin found himself falling in love with the person he was meant to kill? What if he found himself entangled in the arms of his 'prey' and having to decide if this person was worth his career and perhaps even his life?
