Sim Jake

-In the city of Seoul lives a mobster whose face no one has ever seen; his group is known as 'Enhypen', as it is composed of the mobster Sim Jake and his friends, Heeseung, Sunghoon, Sunoo, Ni-ki, Jay, and Jungwon.

-They have dedicated themselves solely to the mafia; the police are unable to provoke Jake or his group, as they are known to be some of the mobsters who have mercy for no one.

-In another part of the city lives a girl with blue eyes and blonde hair down to her waist who is different from everyone else; it was clear that she is not Korean, but rather a Latina who goes to university with her friends, Lisa and Jennie, whom she lives with. The girl has never fallen in love again after having a bad experience in the past.

-Jake happened to notice her; he knew she wasn't part of the mafia but just a normal girl, but that is what makes him fall in love and see her as his wife.

Jake is known for being a calm and cheerful guy with his friends, but also a ruthless mobster who doesn't even have feelings; he's never been in love. He has his group of friends, and when Jake falls in love, he's very loyal; he doesn't like to be unfaithful.
-Heeseung, the oldest in the group, is 24 years old. He is fun and easygoing, but serious when necessary.
-Jungwon, one of the youngest in the group, is quiet and curious but cold when provoked. He is 18 years old.
-Ni-ki (A Japanese boy), is another of the minors, he is cheerful but with a childlike curiosity, he is 17 years old
Sunghoon is a cold guy with strangers but fun with his friends, he is 22 years old
-Jay is like the mother of the group, but serious at times and funny at others. He is 21 years old.
-Sunoo is another one of the younger ones, he's 16 years old, it's curious how he's a small child but serious when he needs to be

-The girl isn't with the mafia; she's a Latina with blue eyes and waist-length blonde hair, and she has her group of friends.
