"I am sorry for hurting you, but I have to do it because I need to go. Don't wait for me, Kim Kibum," Kibum fell on his knees as Yunyu uttered the unknown message that came from his heart.

That apology hit Kibum hard because it was the same apology that Yunyu spoke after Yunyu betrayed him. Kibum pulled Yunyu to his embrace and let out the sentence he wanted to say the moment Yunyu stabbed him with a knife, "Please don't say that. You will only haunt me for the rest of my life with your words."

[Pupa: Ding! Ragemeter decreased to 80%.]

Yunyu responded to Kibum's embrace by hugging him back. Kibum tightened their hugs and whispered, "I should have never found you. I should have stopped Taewoo for trying to hunt your location after you betrayed us. I should have reported you to the police. I should… I should have never met you in the first place."

"I don't care if I will be in my brother's shadow forever. Because this pain was even more excruciating than that. Yunyu, why did you play with my heart? I'm just a fragile, insecure man who longed for love."

Kibum said that, and his hug was getting tighter as he became even more emotional.

[I… I can sense something nostalgic. Something that I have to remember, but I'm unable to. It was like a memory that has been long forgotten. I told Kibum that I had no choice and I need to go, though I don't even know what I'm talking about. It was just a sudden urge to say it.]

[Pupa:… Did you ever transmigrate before you meet me?]

[I am just a normal young man. I never experience anything supernatural or magical until I met you, Pupa. But this feeling is so nostalgic. As if I have experienced this beforehand.]

[Pupa: I don't know either. But based on my data, when I find you, you are just a simple young man, a bit stupid and very shameless, but has a good heart. Maybe this back-up world is just a world to accommodate your wish as a host, or perhaps… this is all happened because you did something in the past.]

[You are scaring me. As evil as I can be, the cruelest thing I ever did was not donating to help Wikipedia stay afloat. And that was because I'm broke as heck.]

Yunyu said nothing but to cater to Kibum's embrace. They stayed in this position for a while until Kibum loosened his hug and stared at confused Yunyu. He scoffed ironically, mocking himself, "I don't even know whether you are acting or not right now. But I still want to forgive and give you another chance. It is so ridiculous that I'm still in love after your betrayal."

Yunyu closed his eyes as he tried to identify this familiar feeling in his heart. But he still couldn't remember anything and said something out of whim again, "Kim Kibum, my heart does not lie. I do love you, just like the rest of them. But I have to do something to save him before he got erased from existence. I have to go even if it hurts you."

"Who is this 'him' and 'them'?" Kibum asked suspiciously.

"I... I don't know..."

[Seriously, I'm so confused. I keep saying stuff that I don't remember. Who is this 'him' anyway?]

[Pupa: Maybe this is the emotion of original Bai Yunyu in this world? The one who betrayed Kibum and Taewoo? Maybe there was someone who transmigrated into this back-up world before you and made all the mess.]

[It is possible. Though, it only makes me even more confused.]

[I don't think I ever transmigrated before I meet you. But this world feels so familiar. Especially since almost everything is an exact replica of my real life, even my face, and name.]

[Did I forget something?]

…

Truthfully, Kibum always expected that Yunyu had men other than him and Taewoo. Knowing his glib tongue, he might have fooled many people. But Kibum was a stupid young guy led by his feeling, as much as he was jealous, the fear of losing Yunyu was far greater.

"Please don't ever leave me again. I just want to stay with you forever, even if I have to share with Taewoo or anybody else. As long as I can see you every day, I am content," Kibum said. He held Yunyu's chin and raised it up until they were staring at each other.

And they shared a kiss.

The kiss was full of passion. As if Kibum had been waiting for this kiss for centuries. Kibum's hand trembled as he tried to suppress his desire for more. Because Bai Yunyu was unpredictable. They might share a kiss today, but Yunyu might stab him again tomorrow.

Kibum separated himself after a while. There were tinges of blushes on his cheeks. He wanted to stare at Yunyu longer, but he was afraid that he would die out of a heart attack because his heart was beating rapidly right now.

Yunyu was more familiar with this Kibum. This was the same Kibum that he liked. He masked his insecurity with cold and aloof poise, just like how Kibum also masked his insecurity by distancing himself from the society in the previous world.

"You owe me a lot of dates," Kibum said, "You promised that you would take me to a lot of popular spots for couples. You must promise me that we will go on a date in the future."

"I promise," Yunyu nodded as he replied.

[Pupa: Ding! Ragemeter decreases to 75%.]

"I will remember that, Yunyu. You cannot run away again this time…"

"I will not run away until you are happy, Kibum…"

[Not that I can leave this world before you are happy anyway.]

"Then, I will meet you again in the school tomorrow. I will tell this to Taewoo because he will also come to you and ask for an explanation. He is also in pain because of your betrayal…"

Taewoo watched everything from afar. He had put a recording device inside Kibum's bag without Kibum knowing, so he could hear what Yunyu said to Kibum. His eyes grew colder as he listened to their conversations.

His older brother was a naïve guy. Taewoo knew that. But he couldn't believe that Kibum would just forgive Yunyu easily. There was no clear explanation, and it was even more confusing when Yunyu said 'him' as if he was referring to someone else other than them.

Bai Yunyu was a treacherous bitch.

"It is obvious that Yunyu is lying again. He will betray us and run away when he has the chance. He didn't even tell us the clear reason behind his betrayal," Taewoo clenched his fist, "Bai Yunyu, you might be able to fool my brother. But you will never fool me! I know that you will betray us again if I don't do something."

"I will show you my pain, Bai Yunyu."
