Yunyu woke up in a room with books and documents stacked up until it created a mountain full of unfinished papers. He was sitting at a desk that had his nameplate on it. Yunyu looked around, hoping that he would at least get a clue on what happened here. But he was inevitably lost as Pupa floated around the room, searching for a hint by itself. 

Pupa returned to Yunyu and said, "I see nothing that can help us identify the situation. But I got information from the headquarter, there is no Breakmeter or Fatemeter in this back-up world, but there is something called Ragemeter. Apparently, it is the thing that caused a glitch in the world. To finish this world, you have to reduce Ragemeter to 0%."

Yunyu frowned. He honestly didn't understand what was happening, but Pupa said that this was the only way to save Kibum and Taewoo. 

Yunyu glanced at the mirror on his left side, and he was astonished, "P—Pupa, who is my identity in this world?"

Pupa downloaded the character information and replied, "Your name is Bai Yunyu. You are in senior year and also the current School president of Yonghwa International School in Seoul. You are currently burdened because you have a nasty animosity with Kim twins, Kim Kibum and Kim Taewoo. They are the new students in this school, transferring for an unknown reason."

"This… this…" Yunyu was astonished by his own appearance. Because this was literally his real face from real life. It was like, he had transmigrated alongside his real body to this world. Even his name was the same. 

The shock was too much for Yunyu that he paused for a good while to process what just happened. Pupa tried to contact headquarter about this problem, but the HQ was uncontactable. Pupa attempted to jump out of the world to go to the HQ, but it couldn't. 

"We are trapped in this world unless you can finish the mission," Pupa informed. 

After Yunyu had recovered from his shock, his first question to Pupa was, "How much is the Ragemeter currently?" 

"100%," Pupa replied short.

"I'm seriously way too shocked by my real face and name that I don't have enough energy to get surprised by that 100% Ragemeter," Yunyu said.

"Don't worry, you can take your time. We will be here for a while."

"What do you mean?" Yunyu asked. He squinted suspiciously at Pupa, "Is this one of your tricks again?"

"I wished. But I said so because other than the information of your character and the twins' characters as the master of the world, I have no other information. I don't know the cause behind their animosity towards you, and I don't know what triggers Ragemeter."

Yunyu felt that something was not right with this back-up world stuff. He transmigrated with his real body and name, something about Ragemeter and how the setting changes, but the master of the world stayed the same. 

As he kept thinking about the possibility, Pupa sensed someone was coming and then turned invisible. 

Suddenly, the school president's office was kicked from outside. Yunyu turned his head at the door instantly, and he saw something even more astonishing. It was too much of a shock for him to handle that his mind just went blank. 

"There you are!" Taewoo said as he kicked the door open. Taewoo wore glasses, just like in his own world, but he had a separate body from Kibum. As Yunyu saw that Kibum was standing silently beside Taewoo. 

Taewoo strutted Yunyu and pulled Yunyu's collar. Yunyu was small compared to Kibum or Taewoo, "I know that you can be such a demon, but you dare to run away after what you did to us?!" 

Kibum tried to pacify his twin brother. He patted Taewoo's shoulder and said, "Don't be rash. Remember, we are just new transfer students. If Yunyu decides to be the snake that he is and reports us, we will be expelled and have no way to watch over him. Remember what he did back when we are freshmen in our previous high school?"

Taewoo gritted his teeth. He was furious at Yunyu because this guy dared to leave them after what he did. But at last, they found him once again.

And this time, they would not let go. They wanted to make this guy suffered for what he did. 

Taewoo released Yunyu's collar and then turned away, "Remember, Bai Yunyu, don't even think about running away again. Because I will always find you. And don't even think about ignoring me."

Taewoo clenched his fist, but he decided to vent his frustration outside and left Kibum alone with Yunyu. 

Kibum stared at Yunyu, whose leg was weak. He couldn't get up at all due to the mental shock. Kibum crouched until he was at the same level with Yunyu. Kibum patted Yunyu's head gently, "Don't worry, Yunyu. I am not as rough as Taewoo. He can be a bit excessive sometimes. But truly, he misses you a lot."

Yunyu stared at Kibum, whose face was a lot more confident than his dull self in the previous world, "Are you really Kim Kibum?" 

"Of course, I am. Why do you ask?" Kibum smiled, but his smile didn't reach his eyes. That eyes were cold as he finally heard the voice that he missed for so long. He missed Yunyu so much that he thought he would go crazy anytime soon. 

"That… I thought that you are…" 

"Hmm? That I am just a dull man, who will forever be overshadowed by my brother? Well, I was, but you are the one who changed me, remember?" 

Yunyu was tongue-tied. There were too many questions in his head for him to process. 

Kibum caressed Yunyu's cheek gently and said, "Don't worry. I will make you remember everything. I will never let you go."

Kibum's eyes were cold, emotionless, and intimidating. Even scarier than Taewoo. Kibum stood up and walked off the school president's office, "I will meet you later. I need to calm Taewoo first before I can play with you. Remember Bai Yunyu, you are mine."
