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 made up of the mobster Sim Jake and his friends, Heeseung Sunghoon, Sunoo, Ni-ki, Jay, and Jungwon.

-They've only ever been involved with the mafia; the police can't provoke Jake or his group because they're known for being some of the most ruthless mobsters.

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

Jake noticed her; he knew she wasn't part of the mafia but just a normal girl, but that's what made 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.
Lisa and Jennie go to the same university; she doesn't like to show weakness in front of people.
