The Archmage Forgot to Turn Off the Stream · Chapter 3

Episode 3. The Subscribers Started Memorizing Seal Arrays

Reader settings

Tune the page before a long night read.

The second thud from inside the wardrobe was louder than the first. The wooden door shoved outward from the inside, and a ribbon of violet mist slipped through the gap. Instinctively, Eun-ha reached out and tilted the phone camera toward the ceiling.

"Brief technical check," she announced.

Naturally, the chat became even more excited.

— why is the technical check purple smoke
— the wardrobe just moved
— this is exactly when you should NOT end the stream

Moro had already spread three talismans across the floor. "The containment seal is opening. It's a residual entity from the fracture you closed tonight. Weak body, terrible temperament."

"Why now?"

"Because you cast a healing spell for a donation. The mana ripple reached the box."

Eun-ha ran a hand over her face. The job of saving the world always included surprise overtime, but usually not in front of thirteen thousand live viewers.

The wardrobe doors flew open. Three black spheres the size of fists bounced out, smooth like condensed smoke. They hovered for a second, then each picked a target: the camera lens, the kitchen light, and Moro's tail.

"Left!"

At Moro's shout, Eun-ha swung the convenience-store bag instead of a staff. The onion ring packet burst against the first sphere, scattering salty powder through the air. To everyone's surprise, the entity lost its direction and began spinning in place.

The chat was still treating the situation like the best staged bit they had ever seen.

— onion rings are its weakness
— boss fight memo: onion rings
— what is that circular symbol on the floor, it's pretty

That made Eun-ha look back at the screen. The circular symbol. Part of Moro's seal pattern was visible in the corner of the frame, and viewers were already trying to copy it.

"Moro."

"What."

"They're looking at the pattern."

He glanced at the chat and looked offended by reality itself. "Is that what you're focusing on right now?"

But Eun-ha was already calculating. Residual entities were not especially strong, only erratic. Guiding arrays worked better on them than brute sealing. The problem was that she had only two hands. If the audience was busy copying the visible geometry, she could at least speak the sequence aloud without it sounding suspicious.

So she raised her voice just enough for the microphone to catch clearly.

"All right, everyone. Production explanation time. Divide the circle into three. Reverse triangle inside. Final marker at the four o'clock position."

The chat repeated the instructions back in real time.

— divide into three
— reverse triangle
— four o'clock marker
— this is absolutely an ARG

Using that rhythm as cover, Eun-ha traced the actual seal in the air. Oddly enough, concentrating became easier. The spoken pattern gave the spell a beat.

The first residual was pulled into a line of gold.

Moro lured the second toward the entrance using an open can lid.

The third was the worst. It circled the streaming gear, blurred the camera focus, and briefly covered the chat with broken symbols. For several seconds the screen filled with static-like characters and rows of ####.

— i thought we were being hacked
— if this is staged it's genius
— save moro

"Moro isn't going to die," Eun-ha shot back almost automatically, then reached for the final sphere. It slipped past her hand, skimmed her wrist, and bounced toward the ceiling. The fire spirit jolted in panic and scattered sparks, causing every light in the apartment to blink out and back on.

In that fraction of darkness, one line at the top of the chat caught her eye.

— just keep streaming, if anything weird happens we'll clip it first

The sentence was ridiculous, and yet it helped. The viewers did not know the truth. But because they did not know, they were not afraid either. No one was screaming run. Everyone was treating this like late-night chaos in a strangely committed live stream.

Eun-ha smiled despite herself.

"All right then. Final effect."

She snapped her fingers and left only a single overhead light on. In the dimness, the violet residual floated vividly in the air. At the same time, the talismans on the floor, Moro's can lid, the fire spirit's flame, and the phone screen each lit one direction.

Eun-ha connected all four points at once and completed the seal.

The residual shrieked inward, shuddered one last time as if it had caught the smell of onion rings again, and vanished.

Silence dropped through the apartment.

The chat froze for about two seconds, then surged harder than before.

— insane
— what even is this channel
— give the production team a raise
— scheduling the next stream immediately

Eun-ha let out a long breath. Moro dropped to the floor and rubbed his face with one paw.

"Can we turn it off now?" he asked.

Eun-ha looked down at the phone. Concurrent viewers had passed twenty thousand. New subscriptions were still popping one after another. A few minutes ago this had been an accident. Now it felt slightly different.

"No," she said.

Moro's ears twitched upward.

"But we are adding more rules."

Facing the camera, Eun-ha bowed her head once.

"That's it for tonight. Starting next time, this will be a more organized late-night everyday fantasy stream. No real names. No exact locations. No requests for live combat sealing. Midnight snack recommendations, however, are welcome."

The chat erupted like applause.

— accepted
— moro vlog next
— fire spirit needs permanent casting
— tteokbokki for the snack choice

Only then did Eun-ha press the end button. The room became so quiet that her ears rang. Even after the screen went dark, the phone kept vibrating with notifications for a long while.

Moro sighed. "Your life is going to get much louder."

Eun-ha stared at the onion ring dust on the floor and the torn talismans around it. Up to now, her life had leaned too far in the opposite direction. She had saved the world, but no one knew, and it had always been safer that way.

Yet the chat tonight had done something strange. By refusing to believe the truth too directly, the viewers had accidentally built her a mask she could survive inside.

"Louder is fine," she said quietly.

"This time I'm not planning to turn it off."

By late morning, the channel had a new name.

Late-Night Everyday Fantasy: Person Who Often Forgets to End Stream

Before sunrise, the subscriber count passed thirty thousand. Pinned near the top was a comment that read:

— I still don't know what genre this channel is, but I know I'm coming back

For the first time, Eun-ha pressed the heart on a comment. After saving the world, her calendar had usually looked blank. Now, for the first time, she found herself thinking seriously about the time of the next broadcast.
