Revenge with the Power of the Final Boss

At 4 a.m., after a long and heated night, Baek Seo-jun stepped outside. Following him were not his usual companions—Seomun Ye-jin, Han Se-hee, or Lee Ha-yeon—but rather Kang Yu-ra and Moriya Yuka.

The two women, now wearing the school uniforms that Baek Seo-jun had handed back to them, followed him shyly. The moment they stepped outside, their expressions shifted into one of fascination.
"360 hours passed inside, but only six hours have gone by out here," said Kang Yu-ra, marveling at the discrepancy.
"Even though this is the second time, it still feels so surreal," added Moriya Yuka with growing astonishment.

Both women couldn't help but feel amazed. Despite it being their second experience, the stark difference in the passage of time—60 times faster within the space compared to outside—remained a phenomenon that fascinated them.
And during that time, much had changed for them compared to before they entered.
First, their bodies were no longer the same as before they had gone in—they were no longer virgins. Their bodies had accepted Baek Seo-jun's seed countless times, and they emerged from the endless pleasure, basking in happiness, with their hearts also transformed.

The way they looked at Baek Seo-jun was no different from how Seomun Ye-jin, Lee Ha-yeon, and Han Se-hee gazed at him.
The long 360 hours had completely turned the deep affection they had held for Baek Seo-jun into pure love.
“You’ll experience it every day from now on, so you’ll get used to it soon enough.”

Baek Seo-jun spoke softly, gently stroking their heads. At this, Moriya Yuka gave a playful smile and said,
“While I do like when you stroke my head... I’d prefer it if you did that outside.”
“Is that so?”

“Yes. But instead of my head, please stroke my backside. Especially under my skirt.”
At Moriya Yuka’s bold request, Kang Yu-ra spoke up with a shy expression.
“M-me too.”

Though she seemed embarrassed, the fiery longing in her crimson eyes was unmistakable. Watching the two women who had now become his, Baek Seo-jun silently slid his hand under their skirts.
As soon as he did, both women embraced him tightly with satisfied expressions. Holding them in his arms for a moment, Baek Seo-jun thought to himself.
‘Somehow, all the heroines of the original story have become mine.’

But whether they were the heroines of the original or not no longer mattered to him. They were special to him simply because they were who they were.
In any case, his goal was to finish his revenge, save the world, and live a quiet life afterward.
What came after that... he would decide when the time came.
‘Yes, I’ll think about that when the time comes.’

For now, what he needed to do was help Moriya Yuka learn to protect herself and her family, and enable Kang Yu-ra to exact her revenge with her own hands. He needed to make them stronger.
“Alright, I’ll help both of you grow stronger quickly.”
“Yes.”

“Please do.”
They already knew about the true strength of Seomun Ye-jin and Lee Ha-yeon. Although publicly known as an SSS-class Hunter and an SS-class Hunter, Seomun Ye-jin’s actual power surpassed even the strongest in the world.
In fact, aside from Baek Seo-jun, she was already the strongest Hunter alive.

Lee Ha-yeon’s strength was already among the best of the SSS-class Hunters. Her level was far beyond that of Baek Seo-jin, who had only just reached SSS-class status.
As for Han Se-hee, while she lacked direct combat capabilities as a healer, she had reached an SSS-class Hunter’s level in her field. The nickname “Saint” wasn’t an exaggeration—it was a testament to her extraordinary skills.
For Moriya Yuka and Kang Yu-ra, the idea of falling behind these women any further was unacceptable. They were determined to grow stronger quickly.

“This is perfect timing.”
Baek Seo-jun spoke as he firmly grabbed their backsides.
“Ah!”

“S-Seobangnim?” (A term of endearment for a husband)
They were startled by Baek Seo-jun’s unexpected action as he claimed he would make them stronger, his hands gripping them tightly. However, his actions weren’t driven by mere indulgence.
His intent was solely to help Moriya Yuka and Kang Yu-ra grow stronger.

‘Yuka will grow like a deep forest. Yu-ra, like a wide river.’
Moriya Yuka’s family name, Moriya, was often misinterpreted in Japan as “forest” due to its pronunciation being similar to the word “mori” (forest). Similarly, Kang Yu-ra’s family name, Kang, could also mean “river” in Korean, even though the characters differed.
Forest and river. While their surnames didn’t literally mean forest and river, the phonetic association allowed Baek Seo-jun to frame their imagery in these terms, using it to guide their growth effectively.

‘And beyond their names, both of them possess the attribute of ice. It feels like fate brought them together.’
Kang Yu-ra, who wielded lightning and ice, and Moriya Yuka, who harnessed wind and ice, had different approaches to their power. However, their shared affinity for ice gave Baek Seo-jun a foundation for considering their combined potential.
‘First, I’ll make them stronger.’

With that thought, Baek Seo-jun began to awaken their latent potential through his touch. His hands, still gripping their backsides, served as a conduit to elevate their affinity for mana and unlock their hidden talents. Utilizing the energy lingering in their bodies from their intimate connection with him, he channeled his power.
Having received his essence countless times, their bodies had formed a deep connection to him.
“Ah!”

“This...!”
Moriya Yuka and Kang Yu-ra felt the surge of energy coursing through them as they closed their eyes. Through Baek Seo-jun’s touch, they realized their bodies had already undergone transformation—so naturally that they hadn’t even noticed.
‘I can sense mana so much more clearly now!’

‘This feeling...!’
The two women experienced an enhanced sensitivity to mana, including Baek Seo-jun’s immense power. Their perception of energy had sharpened significantly. Moreover, knowledge of how to utilize their abilities began to emerge naturally—not as external input, but as a result of their talents being brought to their peak.
They now understood how Seomun Ye-jin, Lee Ha-yeon, and Han Se-hee had managed to grow so rapidly.

‘It was all about elevating their innate talents.’
Rather than implanting new abilities, he had drawn out their existing potential to its fullest. And while they had received some benefits from him even before their intimate connection, the deeper bond they shared now granted them additional advantages.
“Ah!”

“Ahh!”
A lightning-like shock ran through Moriya Yuka and Kang Yu-ra’s minds. They felt Baek Seo-jun’s energy stimulating the remnants of his power within them, transforming it into their own.
The energy he had left inside them was no longer a passive force—it was merging with their own, pushing them to new heights. As Baek Seo-jun’s unparalleled energy integrated with theirs, they began to taste the power of a new realm.

The sensation shattered their limits, guiding them to an entirely new stage.
In Moriya Yuka’s mind, a vast, sprawling forest emerged. For Kang Yu-ra, it was a long, unending river. Alongside their expanded reservoirs of mana, these images solidified their newfound strength—a manifestation of Baek Seo-jun’s influence.
‘I must protect everyone in the Moriya family, like that wide forest...’

‘I must keep moving forward for revenge, like that endless river...’
Both women stepped into the domain of SSS-class Mana Awakeners.
‘It’s done.’

Baek Seo-jun smiled as he observed their transformation into full-fledged SSS-class Hunters. Though they had just reached this rank, they still had room for improvement. Fortunately, he could help them with that as well.
It wouldn’t take long to refine them into seasoned SSS-class Hunters.
‘By tomorrow morning, both of them will be strong enough.’

But Baek Seo-jun didn’t plan to stop at simply raising them to this level. He intended to give them another gift.
***
All five of the original heroines were now my women, and even the healer, Han Se-hee, had reached a level befitting an SSS-class Hunter. In truth, all five of them had effectively surpassed the realm of SSS-class Hunters.

Now, the day of revenge was just around the corner.
My revenge—and Kang Yu-ra's revenge as well.
