Okay, this short fic just depits the life of Sang Hyun (Thunder). He is a spy/assassin/or whatever whose job description all but asks him to kill people. Alongside with his gang (MBLAQ). After a few missions, SangHyun is stressed. Seeing he is still quite new, he's having prolems sleeping due to the memories. His sister, Sandara advises him to get a girlfriend so he won't be too lonely and stressed.

  One day, as he's struggling with sleep, all alone in the apartment, he receives an anonymous guest in the middle of the night. Surrised to find a womaan bby the door in search of his friend Changsun (Joon), he invites her in due to her current condition - that is soaking wet from the rain. He lends her a place to change and probavly stay until the rain stops. As he helps her with the shower, Sang Hyun and her end up in a sticky situation which led to some heated lovemaking.

  As Sang Hyun was getting into it, gives him a surprise.... Therefore, leaves him in the room by himself. He didn't even know her name...
