Quick Transmigration: Homewrecker System!

*Look outside. I am waiting.* 

Yunyu gulped as he watched checked on the window with the curtain shut. He had an ominous feeling, but he felt that something even more troublesome would occur if he tried to ignore it. 

Thus, he walked slowly and then opened the curtain slightly. He peeked, hoping that there was no jumpscare like those in horror movies.

[I swear to god, if there is a Thailand horror kind of jumpscare, I will piss myself.]

[Pupa: Why Thailand horror?]

[Have you ever see their horror movie? Thailand horror movie is like… next level kind of horror. I would like watching it with the real Han Ye, and then act scared and snuggled with him, ehehe...]

[Pupa:… what if you pissed yourself when you are with Han Ye on the couch?]

[… You always find the way to ruin my fantasy.]

[Pupa: It's my hidden talent.]

Yunyu gulped as he peeked. He saw an empty front yard until he noticed a man standing with his calm smile that didn't reach his eyes. He had his phone on his ear as he called Yunyu again. 

Yunyu picked up the phone nervously, "K—Kibum, why are you here? Where is Taewoo?"

"I told him that this is my time to find you first since I am the older brother. Why? Are you scared that someone barged in your house like this?" Kibum scoffed as his cold eyes stared directly at Kibum on the second floor, "You did the same to me. You barged into my heart and changed everything. Do you ever think about the consequence?"

Yunyu was really lost, he didn't know what Kibum was talking about, but he assumed it was about their past.

"Come out, I want to see you again," Kibum said. His tone was not crude, but he was demanding. No, rather than demand, it was more like a threat. Yunyu's hand trembled, but he stayed calm and asked;

"If I come out, will you be more civil and talk with me slowly?" 

"I will never hurt you, Bai Yunyu." 

With that answer, Yunyu decided to believe Kibum and walked downstairs. Truthfully, he was terrified about Kibum and Taewoo right now. He had no idea about this world, and they had Han Ye's face. It hit him on a personal level. 

But if he tried to ignore these two, then he would be stuck in this world forever. Yunyu decided to unlock his front door to meet Kibum, who already stood on the terrace. He had a cold smile on his face, still with his student uniform. Yunyu hid behind the door, afraid that Kibum might bring a knife or something.

"Bai Yunyu, you are brave enough to open the door. I applaud you for that," Kibum said. Yunyu took a step back instinctively;

"W—What do you want?" Yunyu asked nervously. 

"… I just want to know about something," Kibum took one step in to close his distance with Yunyu. Yunyu took another step back out of reflex. Which made Kibum displeased, "Are you really scared of me? Or is it the guilt that made you act like a cornered little bunny? Stop it, Bai Yunyu. You are the one who said to me that you have no guilt or regret." 

"I…" 

[Pupa, if I said that I don't know anything at all, will he believe me, or will we have to restart and fail this world?]

[Pupa: I don't know. I don't have any information about this world.]

[… why do I even ask?]

"I… am sorry…" Yunyu apologized. He didn't know what he was sorry for. But maybe this would pacify Kibum and decrease the Ragemeter. 

But to his surprise, Kibum glared at him and kicked the door. 

"Ah!" Yunyu lost his balance as Kibum kicked the door. His butt landed on the cold floor as Kibum looked down on him;

"Never say sorry to me, ever again," Kibum said. His heart was cold when Yunyu apologized to him, "You said that only to trick me. Yunyu, you are such a terrible snake."

Yunyu was confused as he kept on guessing what Kibum meant with that. He was scared and also frustrated at this mission. Because he was left in this world to save them, but they treated him like this.

"I… really mean it…" Yunyu said. 

Kibum ignored all his plea and then crouched in front of Yunyu. He unbuttoned his school uniform in front of Yunyu, but his eyes were still unfeeling. 

Kibum showed a scar on his chest. It was a deep scar that should be fatal for regular people, "Why did you do this to me? Why did you stab me but intentionally missed my heart? What is your point of doing so? Bai Yunyu, you should've stabbed me right on my heart. Because the moment you attacked me, my heart has been died since."

Kibum pulled Yunyu's hand, and he rudely placed Yunyu's hand on his scar. Kibum's face was full of pain as he tried his best not to cry, "This is what you did to me. At first, I thought you betrayed me because you want to stay with Taewoo. But turns out, you also did the same thing to him."

"What is this all about, Bai Yunyu?"

Yunyu stared at the scar and then stared at Kibum, whose eyes welled up. Although Kibum had changed, he still had the same fragile insecurity deep inside his eyes, just like Kim Kibum in the previous world. Yunyu observed long enough to tell that Kibum had a deep resentment and sadness in his heart. 

And apparently, it was the Bai Yunyu of this world which caused Kibum's heartbreak for an unknown reason. 

Yunyu caressed the scar on Kibum's chest. It was a deep scar that would last forever, like a mark of his betrayal. Somehow, his heart was also pained when he touched the scar. Yunyu felt that this wound reminisced something that he forgot a long time ago.

"I am sorry, Kibum," Yunyu said. His voice trembled as he started spouting the words in his heart. It was like a message that should have been conveyed a long time ago, but he had no time for it because he had to leave, "I am sorry for hurting you, but I have to do it because I need to go. Don't wait for me, Kim Kibum."
