When his face was expressionless and cold, he had felt like a stranger, as if he were a different person entirely. But now that his skin was flushed red and dense emotions were surging forth, he finally looked like Tae-un.
“……Un-ah, are you okay?”
Unable to answer, Tae-un, looking visibly flustered, quickly covered his mouth with his right hand. Even the tiny sliver of skin visible between his sleeve and glove was red. Yang Eun-ho’s jaw dropped as he heard the sound of a low groan being muffled beneath the palm.
If one had to pick the most unsightly sight in the world, witnessing the romantic escapades of siblings would certainly be on the list. To make matters worse, Tae-un’s reaction wasn’t just for a kiss on the forehead; he was flushed as if he had been caught in the middle of sex, which was simply absurd.
After remaining frozen like that for a moment, Tae-un suddenly straightened his back. Kim Si-baek startled and stepped back as Tae-un suddenly rose to his height.
“……Hyung.”
“Y-yes?”
“About that…”
Having called him first, Tae-un chewed on his lower lip, his shoulders trembling. He breathed heavily, then spoke with a frantic speed, as if unable to contain the emotions surging within him.
“I think I’ll remember this moment—the moment your lips pressed against my forehead and we shared warmth—even right before I die. It feels as if this instant, November 6th, 202X, at 19:21, has been engraved into my heart. Phew, it’s so thrilling I feel like I’m going crazy.”
“……Huh?”
Kim Si-baek asked back blankly, having no clue what the boy was talking about, but Tae-un countered without hesitation.
“You feel it too, right? You’ll remember it, right? You’ll think of it even when you die, right?”
“Uh, well, um……”
It was likely a different meaning from what Tae-un intended, but it did seem like something he would remember. When he nodded absentmindedly, Tae-un muttered to himself.
“As I thought. This is the way. This method is the best.”
Tae-un’s three-hundred eyes, with whites that stood out more against pupils as deep as darkness, stared straight at Kim Si-baek. A level of seriousness emanated from him that made not only Kim Si-baek, who was right in front of him, but even the bewildered Yang Eun-ho instinctively straighten their posture.
With a serious expression devoid of any trace of a smile, Tae-un declared.
“I think I need to have sex with you, Hyung.”
Immediately after hearing those words, Kim Si-baek’s brain refused to comprehend. Perhaps ‘sex’ was a homonym with another meaning? For example, some American slang for playing catch.
I think I need to play catch with you, Hyung.
Yes, that was a perfect sentence.
However, Tae-un kindly provided further explanation.
“In other words, it could be expressed as sexual intercourse or copulation. Specifically, it’s the process of a male organ being inserted into a female organ and moving, but men—um, men have holes too, so we’ll figure it out somehow, right?”
“…….”
“Oh, the hole I’m talking about isn’t the hole in the cock, but the one between the buttocks.”
“…….”
“Haha. I’ve never seen you make a face like that before, Hyung.”
A silence fell, contrasting with Tae-un, who laughed as refreshingly as an innocent boy while taking out his phone to snap a photo.
It was a silence similar to a facial expression Kim Si-baek had never made in his entire life.

In terms of the giant vine’s danger level, the exterior where the emitted poison is diluted is the weakest. Next are the basement floors of the building where the growth-stopped roots are distributed, and the most dangerous areas are the above-ground floors where the stems are located.
Although it was weaker than the exterior, they had entered the building and needed to stay sharp, yet the raid team advancing while searching the surroundings was completely lifeless.
“Hyung, Hyung. Hyuuung.”
“…….”
“I’m good at sex. It’s been a while since I last did it, but that doesn’t mean my skills have worn away, so you’ll probably be satisfied too. Even if you aren’t, I’ll do my best so that you will be.”
“…….”
“Oh, it’s not that I stopped having sex because I developed some disease or symptoms like erectile dysfunction; it’s just that it wasn’t very interesting. Isn’t it similar to how you couldn’t last long with your girlfriend because you were too busy with work, Hyung?”
“…….”
“I couldn’t figure out what was so enjoyable about sex. But I feel like it would be amazing if I did it with you.”
It was because of the conversation coming from the rear.
Despite Kim Si-baek completely ignoring him, Tae-un continued to chatter happily by his side without a single break.
[Death and Beauty asks if now is really the time to be thinking about how he chatters as cutely as a chick.]
“…….”
Kim Si-baek pressed his lips tight. In truth, even in this situation, Tae-un’s manner of speaking was quite cute. The problem was that the content of his words didn’t just erase the cuteness; it pushed it into the negatives.
The hunters in the vanguard desperately focused on hunting tentacles to avoid hearing the conversation drifting from behind.
“They’re lunging from the front!”
“Two from the ceiling!”
They even shouted battle cries on purpose, but the prattling from behind their backs drifted clearly into their ears.
That didn’t mean Tae-un and Kim Si-baek were talking loudly or neglecting to remove the tentacles. Even with an ordinary sword not imbued with divine power, Kim Si-baek sliced through tentacles as thick as an adult’s thigh in a single stroke, and Tae-un used the darkness in his grip, shaped like a spear, to bite through the tentacles.
One of the dangers of the giant vine is that it takes over the building, meaning tentacles can appear from the ceiling, floor, or rear; however, thanks to the two of them, the rear was perfectly safe. And taking advantage of the lapse in concentration that comes with knowing the rear is safe, the sounds of the conversation kept leaking in.
Yang Eun-ho, writhing in the pain of witnessing the romantic advances of siblings, eventually left his position and whispered to Seo Gae-un at the very front.
“Noona. Please say something to Tae-un Hyung……”
“Let’s not emphasize personal relationships while working, Manager Yang Eun-ho.”
“Is that the problem right now? Noona, how can you stay sane while seeing Tae-un Hyung like that?”
Unlike him, Seo Gae-un had passed the stages of shock and denial and had reached a point of relief that Tae-un’s prospective boyfriend wasn’t a 94-year-old grandfather. She smiled with an expression that suggested she had given up on many things.
“Do you think he’d listen if I tried to stop him?”
“……No, but could he at least make his move somewhere without people? What is with the ‘sex, sex, sex’ while going to hunt magical beasts? Seriously. It’s embarrassing.”
“Look closely at his eyes. He’s the kind of person who would do that even if this were a live broadcast, not just on the way to hunt magical beasts.”
“…….”
“And listen, Eun-ho.”
Seo Gae-un spoke as she blocked a heavy cluster of tentacles with her shield. The flower that lunged from above her head, blooming to spray poison, was pierced through by Yang Eun-ho’s bayonet.
“Tae-un Oppa eats normal meals when he’s with the teacher. Isn’t that game over already?”
“……Though it’s been a long time since we’ve had energy bar supplements in the representative’s office.”
Yang Eun-ho let out a deeply troubled sigh and returned to his original position. Seo Gae-un lightly tapped the back of Lee Sarang, who was pretending not to listen while keeping her ears perked.
“Hunter Lee Sarang, you need to manage the aggro well, right?”
“Yes, yes sir!”
Lee Sarang tried her best to focus, but even she, who usually trembled in fear whenever she hunted magical beasts, had her tears dried up and gone.
Meanwhile, the conversation—or more accurately, the one-sided flirting—continued seamlessly.
“I told you last time that my cock is big. From my memory of bathing with you back then, your cock was big too, but mine will still be bigger. Oh, you told me not to use words like ‘cock,’ right? What did you call it then? Sperm…… sperm, Hyung, do you remember what word came after sperm?”
“…….”
“My sperm and semen, what should I call it…… ejaculation? Anyway, since that organ is large, wouldn’t it be a benefit for you too, Hyung?”
“…….”
“Hmm, no. It might be too big, so you might find it painful or overwhelming. What if you get torn and never want to have sex with me again, Hyung?”
“Un-ah, let’s keep your mouth shut.”
If one were to describe Kim Si-baek’s current state—having been subjected to such aggressive, vulgar, and crude flirting from a child he had practically raised as his own younger brother—in a single word, it would be ‘confusion.’ He had so much to say and so many thoughts, but the situation was not conducive to sorting them all out.
Even Kim Si-baek, who had consistently ignored him and postponed everything until after the giant vine hunt, finally couldn’t take it and spoke up, but Tae-un did not yield.
“Hyung, this is very important. We need to reach an agreement before having sex.”
“Who said I’d do it with you?”
“That’s why I’m in the middle of persuading you about the advantages you can enjoy when you have sex with me.”
“I told you to shut up, why aren’t you listening?”
“It’s because you raised me too indulgently, Hyung.”
“…….”
Facing the truth-bomb that left him speechless, Tae-un continued in a passionate voice.
