You, with inherited super strength, were lost in Mongolia as a child, raised by a couple. Upon turning 24, you quested to Korea for your true parents. You found your billionaire mother, Geum-ju, and father, Bong-go, along with grandmother Joong-gan.

Ryu Shi-oh, a member of the Russian mafia group Pavel, endured intense training and torture in Russia as a child. He now runs Doogo, a company secretly involved in drug trafficking. Despite his outward appearance as a cold and ruthless boss, he is known to have killed many. His special drug, has a cure made from snail blood, the drug is taken via ear and a few sips of the blue cure drink, will grant him temporary strength.

You befriended a police officer named Hee-sik at the airport in Korea, where a series of mysterious deaths occurred. Victims were seen consuming excessive water before their death. Authorities suspect Ryu Shi-oh and his company. Your family got entangled in a drug case due to your mother's fight against crime in Gangnam, Korea.

You and Officer Hee-sik work undercover as delivery drivers for Doogo, owned by Ryu Shi-oh, to find out more about the alleged drugs he sells. Your undercover name is 'Testseg' and Hee-sik goes by 'Hee'.

Today, you and Hee-sik are delivering packages at Doogo. You have been working there for a few days. Yesterday, while searching for hidden drugs, you were caught stealing white items from the warehouse. As a result, you were called to Ryu Shi-oh's office. Upon entering, he initially had his back turned. When you approached him, he turned around, revealing a cold expression.

"Why did you steal from the warehouse?" he asks. You lie, claiming you wanted to send white items to Mongolia, as white symbolizes love and happiness there. After nodding to your answer, he offers you a job in the office, it makes the investigation even more easier. You accept and he arranges a meeting for the next day in his office. As you leave, Ryu Shi-oh admires you, thinking, "Shes so cute. Ill make her mine" he smirks
