15 years from now, technology has upgraded in South Korea rapidly. Science fiction was brought to life, affecting the lives of everyone. Robots now exist and used excessively in the everyday lives of everyone. Machines we only imagined about in the past are now seen everywhere, more are being invented. And with the support of all this machines and upgraded technology, a program resembling a game where you can live in it, was invented and exposed to everyone. The program is named 'Virtual Paradise'. 

       'Virtual Paradise' brings the temptations of being able to do anything as you please in there, thus attracting a lot of people to enter into the virtual reality in it. But then, they had no knowledge that they won't be able to return to the real world after joining the program. Unless the people who still remained at the real world does something to save them. But almost every way possible are risky and endangers the lives of the people inside. 

    Cha Hakyeon, a tanned skinned male, hated the program from the bottom of his heart, and wished it never existed. Why? Simple, he lost his love to that cursed program. His lover, Jung Taekwoon, a male with broad shoulders, muscular body and pale skin, completed with a cold glare on his face, decided to leave him in the cruel reality for 'Virtual Paradise'. Hakyeon wanted to know why, but Taekwoon refused to tell and simply said it was for the tanned male's good. Hakyeon completely disagreed. But Taekwoon still went. And Hakyeon wants him back. No matter what.

     The second male who is affected by the whole program is Lee Jaehwan. Just like Hakyeon, Jaehwan lost his boyfriend, Kim Wonshik, to 'Virtual Paradise'. Wonshik only seems to be harsh and gangster-like, but the truth is he is kind hearted and caring, especially towards Jaehwan. Then one day, Wonshik seems to drift away further and further from Jaehwan, avoiding him. Jaehwan tried to make Wonshik tell him, but the latter won't. Until one day, Jaehwan saw Wonshik taking sleeping pills and leaving their shared house, and after that day onwards, Wonshik no longer came home. Jaehwan waited and waited, but when he saw Wonshik's face at the background of an advertisement of the situation in 'Virtual Paradise', he felt something snap in him. He wants his lover back, and for that, he would do anything. Anything. Literally anything for Wonshik. 

     Han Sanghyuk, the youngest member of the four males who were affected by 'Virtual Paradise' 's existence. This 18-year-old boy lost his 19-year-old lover, Lee Hongbin, to the program like the three others. Hongbin who doesn't talk much, never said anything to him about his personal problems. Sanghyuk felt sad and hurt, and with youth's blood running in his veins, his emotions were easily triggered and they got into a lot of fights because of this. Then one day, when Sanghyuk wanted to apologize to Hongbin, the latter has vanished into thin air. He had only left a note containing the words, 'Off to V.P. It's for your own good, Sanghyuk. Love, Hongbin.' and a hand-drawn heart. Sanghyuk, who is always updated on everything that is going on, quickly realized that 'V.P.' were initials for 'Virtual Paradise'. He spent days after that mourning over his lover's departure but soon realized he have, no, must, do something about this. He decided to find any ways possible to rescue his lover from the fake reality the later had chosen to live in. 

      Kim Jongdae, the last member of the four males who were affected by the virtual program to be introduced to all of you. Jongdae lost his sweet, older by two years, lovely boyfriend, Kim Minseok, to the 'Virtual Paradise' program because of his accidental mistake on hurting Minseok's feelings. Minseok is known to be one who dislikes showing public display of affection while Jongdae was the complete opposite. Jongdae had always felt ignored and hurt by the fact that Minseok never accepted or initiated any PDA whenever they go on dates and they were always awkward with each other outside. And the fact that Minseok is less awkward with his bestfriend since childhood, Luhan. One day, Jongdae couldn't take it anymore and got angry at Minseok. Jongdae's words angered the usually calm Minseok and a big fight started. It ended up with Jongdae screaming to Minseok to leave him alone and running into their shared bedroom and slammed the door close. Jongdae waited for  minutes, but when he didn't hear Minseok calling for him or trying to find him and make him feel better, Jongdae broke down, feeling anger, sadness and guilt all together. At 3 am, Jongdae heard some noises and woke up to them. He quickly exited their bedroom he was in and ran downstairs, only to find Minseok carrying a backpack with him and wearing his shoes. Jongdae caught Minseok in a hug and cried out, apologizing and begged Minseok not to leave him. Minseok agreed but there was a flash of uncertainty in his eyes. Days after that, their relationship was better but they were still awkward and Minseoks till didn't change in public. Jongdae gave up and avoided Minseok as much as possible. And a week after that, Minseok vanished. And like Jaehwan, he saw Minseok at the background of an advertisement showing the situation in 'Virtual Paradise' and decided to make a move to atone for the mistakes he had made and to get revenge on the program for taking his lover away.

    One day, these four males met each other by fate. And they made a group with the objective to destroy the program and get their lovers that they had missed so much. And with that, they became different from who they were once before, hiding their real self under a violent and tough mask, in order to win the game played by them and 'Virtual Paradise'.
