The explosion didn't register as sound.
It came as a sudden, violent void where the air used to be, followed by a pressure wave that cracked stone and sent lesser mages diving for cover. Debris rained down in jagged pieces. Dust billowed outward like a living thing.
Ma Yuseong stood in the center of the crater he had just created, Edmary Etemiri gripped white-knuckled in his hand. The upper-intermediate wand hummed with residual energy, its core still blazing from the spell he'd unleashed. His dark blue hair was wild, matted with dust and something darker. His scarlet eyes swept the destruction with cold precision.
Not enough.
Not even enough.
Three bodies lay crumpled at the edges of the blast zone—enemy mages who had thought themselves clever, lying in ambush. They had targeted the supply route. They had picked the wrong moment. They had made the mistake of existing within Yuseong's line of sight when he rounded that corner and saw—
He didn't finish the thought.
Couldn't.
Because if he finished the thought, he would stop being efficient. And right now, efficiency was the only thing keeping him from burning everything to ash.
"Yuseong!" Someone was shouting his name from a distance. Wonryang, maybe. Or Flame. It didn't matter. They weren't important.
He was important.
Yuseong moved.
His feet carried him across the broken ground, past smoldering craters and the groaning bodies of the fallen. He didn't look at them. They weren't worth his attention. His focus was a razor's edge, cutting through everything except the single point that mattered.
Baek Yuseol lay slumped against the remnants of a collapsed wall.
The sight stopped Yuseong's heart for exactly half a beat. Then something else surged in to fill the space—something hot and black and venomous, coiling through his veins like liquid fire.
He dropped to his knees.
Yuseol's face was pale. Too pale. Blood streaked down his temple, matting his brown hair to his skin. His amber eyes were closed. His chest rose and fell in shallow, uneven breaths—still breathing, still alive—but his right arm was bent at an angle that made Yuseong's vision go red at the edges.
Terivon lay on the ground three feet away. Yuseong didn't care about the wand.
"Yuseol." His voice came out wrong. Flat. Dead. Nothing like the playful tone he wore like armor. "Yuseol, open your eyes."
No response.
Yuseong's hand trembled as he reached out, fingers pressing against the side of Yuseol's neck. A pulse. Weak, but there. The relief that shot through him was immediately consumed by the rage waiting underneath.
Someone did this.
Someone touched him.
Someone hurt what's mine.
"YUSEONG!"
Wonryang's voice was closer now, panicked. Yuseong ignored him. He gathered Yuseol into his arms with a care that contradicted everything burning inside him—one arm under Yuseol's shoulders, the other supporting his injured arm as gently as possible. Yuseol's head lolled against his chest. His breath ghosted warm against Yuseong's collarbone.
Alive.
Yuseong closed his eyes for a single second.
When he opened them again, they weren't scarlet anymore.
They were red. The color of fresh blood. The color of warning. The color of a man who had stopped pretending to be approachable, stopped hiding behind lazy smiles and casual indifference.
Ma Yuseong was gone.
Something far more dangerous had taken his place.
"Who else?" he asked.
Wonryang skidded to a halt a few meters away, chest heaving. He took one look at Yuseong's face and went very still. "What?"
"Who. Else." Each word was a separate sentence, a separate blade. "There were more than three. I felt their traces. Where are they?"
"Yuseong, you need to get him to the infirmary—"
"WHERE?"
The word cracked through the air like thunder. Wonryang flinched. Around them, the remaining academy personnel had gone quiet, watching the scene with wide eyes. No one moved. No one breathed.
Yuseong felt Edmary Etemiri pulse in his grip, responding to his emotional state. The wand had chosen him for his potential, for his capacity. Right now, it was drinking in his fury like fine wine.
"The northern ridge," Wonryang said finally, voice tight. "There's a second group. They were the ones who set the trap. These three were just—"
"Bait." Yuseong's lips curved into something that wasn't a smile. "I know."
He looked down at Yuseol's unconscious face. The fury inside him didn't diminish—if anything, it sharpened, focusing into something precise and lethal. He would burn the eastern ridge to nothing. He would make sure every single person involved in this attack understood what it meant to touch someone under his protection.
But first—
"Take him," Yuseong said, turning to Wonryang. "Get him to the infirmary. Don't let anyone else touch him. Don't let him wake up alone."
Wonryang hesitated. "What are you going to do?"
Yuseong gently transferred Yuseol into Wonryang's arms. His fingers lingered for a moment on Yuseol's cheek, wiping away a smear of blood. Then he stood.
Edmary Etemiri blazed in his hand, its upper-intermediate core glowing so bright it cast shadows across the crater.
"I'm going to finish it."
The northern ridge burned for three hours.
They said later that the sky turned orange even though the sun had already set. They said the temperature in the surrounding area rose ten degrees. They said Ma Yuseong walked out of the flames alone, unharmed, his wand still smoking, and didn't say a single word to anyone for the rest of the night.
They didn't say what they found in the aftermath. They didn't talk about the second group—how many there had been, or what state they were in. The academy suppressed those details.
But everyone remembered the look on his face when he emerged.
It wasn't rage anymore. It wasn't cold or calculating or even particularly threatening.
It was empty.
Like something had hollowed him out from the inside and left only the shell behind.
Yuseong sat in the chair beside Yuseol's infirmary bed for six hours without moving.
He didn't sleep. Didn't eat. Didn't respond when people came to check on him. His scarlet eyes—dulled back to their normal shade, though dimmer than before—remained fixed on Yuseol's face, tracking every breath, every twitch, every sign of consciousness.
The healers had done their work. The arm was set. The head wound was closed. Yuseol would recover.
But Yuseong didn't relax.
Couldn't.
Because every time he closed his eyes, he saw Yuseol crumpled against that wall. Every time he breathed, he smelled the blood. Every time his heart beat, it beat with the memory of that single frozen moment when he hadn't known if Yuseol was alive or dead.
I can't lose this.
The thought came unbidden, unwelcome, and utterly undeniable.
Yuseong reached out and took Yuseol's hand. It was warm now—no longer cold with shock, but alive, alive—and he held it like a lifeline.
"I'm here," he said quietly, to no one. To Yuseol. To himself. "I'm not going anywhere."
He didn't say I'm sorry.
He didn't say I was scared.
But his grip tightened, just slightly, and for the first time in hours, something other than fury flickered across his face.
It looked almost like fear.
