The Academy's NTR Villain

The Restricted Rune Archives were almost completely empty at this hour.

Late afternoon on a Wednesday. Most second-year students were either at the outdoor training grounds practicing spell formations or attending supervised self-study in the main hall. The archive entrance required a student-rank stamp above the 60th percentile to pass through the enchanted barrier, which cut the usual student crowd to almost nothing.

I had obtained a temporary research permit through the scholarship office.

The official reason I wrote on the parchment form was "historical residual mapping — continental fault lines."

The real reason was the sealed Black Sun records stored in Shelf Row Seven.

---

I found the shelf without trouble.

Row Seven sat at the far end of the archive, tucked deep behind the heavy stone pillars. Narrow aisle, low ceiling, the kind of forgotten corner the academy administrators had clearly neglected for decades. The stones here were much older than the rest of the building—different colour, different cut, fitted with thin runic seal lines that hummed with faint magical frequency if you pressed a palm flat against the wall.

I pulled a thick, leather-bound document down from the upper rack and opened it on the wooden reading stand.

The Calamity Event Surveys. Three hundred and forty years old. The handwriting was dense, dark, and uneven, the kind of script that came from someone writing fast under extreme pressure while magic flared around them.

I skimmed the yellowed pages carefully.

"...the Black Sun Calamity of the Third Imperial Age was sealed through collective suppression by seven Fourth Ascension mages and above. The primary seal is located approximately four kilometers beneath the academy’s eastern wing. Current seal integrity: stable. Monitoring recommended for sudden fluctuations in continental mana veins, specifically during high-mana events such as dungeon breaches..."

I turned the page, my eyes tracking the faded ink.

"...repeated observation suggests the deep seal produces a passive residual field that seeps upward through stone strata. Mages with compatible core structures may draw this residual unconsciously. Left unchecked, raw residual absorption without a high-bloodline stabiliser produces core corruption, mana inversion, and ultimately, a host-stage Calamity eruption..."

I stopped on that line.

Host-stage Calamity eruption.

I already knew that risk in rough terms from my knowledge of the original novel’s lore. But reading it written out plainly in a three-hundred-year-old official document made my chest tighten in a very real way.

Without Elara’s Ice bloodline filtering and cooling the raw residual during our nights together, my internal core would have started corrupting from the first week. I was already absorbing residual energy from the ground before I had any plan to manage it. If I hadn’t run into Elara by chance, the academy research board would have flagged me as a dangerous risk long before the first term ended.

I thought about the upcoming dungeon expedition. Floor Twelve. Two weeks away.

The Black Sun seal was notoriously thin down there. The survey document said so explicitly: "Fluctuation during high-mana events such as dungeon breaches."

If my core flared uncontrollably during a monster breach in a sealed stone corridor twenty floors underground, surrounded by Lucien and the expedition board’s assigned monitors...

I closed the heavy document and set it back on the wooden shelf.

Soft, light footsteps sounded from the far end of Row Seven.

I didn’t look up right away. I reached for the second document on the rack, a thinner volume titled "Seal Integrity Studies — 2nd Interval Mapping."

The footsteps slowed as they entered the aisle.

Then stopped completely.

I looked up from the reading stand.

Celestia Raine stood at the other end of the narrow aisle, a leather-bound notebook open in one hand and her silver pen cap held loosely in the other. She wore her neat blue blazer. Her pastel-blue hair was tied back cleanly, though one small strand had fallen loose against her cheek—the way it always fell when she had been reading for hours.

She looked at me.

Neither of us spoke for a long, heavy second.

She didn’t look panicked the way she had across the open courtyard yesterday. She looked quieter than that. Tired, maybe. Like she had spent the previous night sitting alone in her room, being very still and struggling with something she couldn’t fix.

"I did not know you used this section," she said softly.

Her voice was level and composed. No tremor. She had clearly decided to maintain her noble posture if she encountered anyone here.

"The research permit was available," I said, keeping my tone neutral.

"Yes." She glanced at the stone shelf near her hand. "House Raine has a standing research allocation in Row Seven. Arcane bloodline genealogy."

"Then we’re both here for the same shelf."

"It seems so."

She took two slow steps closer, pulled a narrow leather volume off the shelf above my eye level, and set it open on the reading stand two feet to my left. She looked down at her page. I looked back down at mine.

The archive was completely quiet except for the low, rhythmic hum of the runic lines embedded in the old stone walls.

One minute passed. Then two.

"I stopped," she said quietly.

I turned one page without answering.

"Like you told me to." Her voice stayed the same—even, low, and clear. "I stopped going to the east path. I stopped leaving doors open. I stayed away from every corridor I knew you used."

"Good."

"It did not help."

The words came out flat. Not dramatic. Not a complaint. Just a plain, honest statement, the way a scholar would report the result of a failed experiment.

I looked up from the document.

She was still staring down at her open page. Her silver pen tapped once against her notebook. Her jaw was set tight. She had clearly decided before walking into this aisle that if she ran into me today, she would say it plainly without trying to hide behind polite excuses.

"I know," I said.

She did look up then. Her violet-blue eyes met mine across the two feet of space between our reading stands. Something moved across her face—not shock, but more like a quiet relief, the small relief that comes when someone confirms what you already knew and you don’t have to pretend otherwise.

Then she looked back down at her page.

"I am not asking for anything," she added, her voice dropping lower. "I am not going to start looking for you again. I just wanted you to know that the problem was not fixed by following the instruction."

"I understand."

Her pen moved across the paper. She wrote a short line in her notebook. I turned another page of the seal report.

The steady hum of the stone walls filled the silence between us.

"The expedition squad list came out this morning," she said after a long pause.

"I saw it."

"You are on my squad."

"Yes."

She wrote another line in her notebook. Her handwriting was precise, small, and neat. High-noble schooling—every letter uniform in size and slant.

"Floor Twelve has unstable mana readings this term," she said softly.

"I know."

"Lucien already spoke to the Expedition Commander. He wants me positioned in the rear ward behind the knight shields."

"He told you."

"This afternoon." A short, bitter pause. "He always tells me what he has already arranged. After he has already arranged it."

I didn’t answer that. There was no neutral way to comment on her fiancée’s political maneuvers without picking a side.

She closed her notebook slowly, the leather cover making a soft thud. She lifted the thin volume off the reading stand and tucked it back into its exact slot on the shelf, the way someone did when they had been trained from childhood to leave everything in its proper place.

She picked up her pen and notebook and turned to go.

Then she stopped with her back still turned toward me.

"I know you have a reason for everything you do," she said, her voice barely louder than a whisper against the stone wall. "I know you are not careless. I know what you said in the shed was true. The risk was real."

"Yes."

"I just cannot make myself stop." Her voice was very quiet now. Quieter than it had been in the shed. "I don’t know what that says about me."

She walked to the end of the aisle and turned the corner into the main hall without looking back.

Her light footsteps faded away into the distance.

I stood in the narrow aisle alone, listening to the old rune-lined walls humming in the quiet space.

I looked down at the Black Sun survey document resting open on the wooden stand.

Host-stage Calamity eruption.

Then I thought about the way she had said those last words.

*I just cannot make myself stop.*

Not said to provoke me. Not said to test my reaction. Said in the exact same tone she had used to report the failed result of keeping her distance. Plain. Accurate. Honest. Like she had looked at her own feelings honestly and given the true reading without trying to pretend.

I closed the survey document and pushed it back onto the shelf.

She wasn’t playing games.

She was drowning in a physical need she hadn’t asked for and couldn’t control, the exact same way the raw residual inside my core had built up before I learned how to manage it.

I picked up my research permit and walked out of Row Seven.
