Twelve K-Drama Episode 7, O-gwi ran through the woods with Mirr in his arms. Sa-min chased from behind. While escaping, O-gwi struck a mountain wall and collapsed. He lost consciousness.

The scene slipped into the past. O-gwi once held Mirr from behind. They laughed and kissed under soft sunlight. They walked around, smiling as if nothing in the world could harm them.

He spoke about his work. He said he could only spot evil spirits, while angels got to protect humans. It made him feel small.

He said he used to pray quietly. Marok was once human, and God gave him powers after long prayers. O-gwi hoped he could be like that too. If he gained powers, he could stand beside angels as an equal.

Mirr warned him. She said such prayers were dangerous. Their talk turned into an argument. But O-gwi stayed calm. He told her even if he never got powers, even if angels never accepted them, he would still love her.

Somewhere else, Sa-min waited. He was the leader of evil spirits, waiting for the hellmouth to open. Meanwhile, O-gwi prayed again and again. He prayed through seasons until he fainted. That was when Sa-min arrived, possessed by darkness.

Broken Faith and Mirr’s Tears

Sa-min whispered to him. He said God would never give him powers. He tempted him to take power greater than angels. Sa-min cut his own hand and poured his blood on O-gwi. That blood made O-gwi an evil spirit.

But O-gwi didn’t follow his orders. Sa-min wanted Mirr’s stone to gain more strength. O-gwi refused. He told Sa-min they were not equals, just because darkness took over his body.

Later, O-gwi met Kangji in the forest. She asked why he betrayed them. He shrugged and said he was bored.

Kangji told him it wasn’t too late. He could still come back. O-gwi replied that he had prayed countless days, but God never answered him.

When Mirr found out O-gwi became an evil spirit, she broke down. She cried until her voice cracked. She looked helpless, she couldn’t even bring herself to speak his name.

Twelve Episode 7 Explained: Memories Return, Hearts Break

Back in the present, O-gwi opened his eyes. A glowing pearl floated and sank into Mirr. She woke up too.

Her memories rushed back. She remembered him, their love, and his fall. They faced each other. Neither spoke. Mirr walked away, her face cold.

Evil spirits had spread everywhere. They hunted humans and turned them into spirits. The world around them burned with chaos.

The angels had regained their powers. They began to heal the wounded. Bang-wool and Kangji searched for evil spirits by smell. Taesan and Kangji attacked and destroyed many of them.

Mirr tracked Sa-min. She tried to call him out, but his army of spirits surrounded her. She unleashed her wind powers.

The spirits scattered. But Sa-min was too strong. His dark force overwhelmed her. She collapsed and fainted.

The angels tried to find her. O-gwi appeared to them. He told them Sa-min had taken Mirr. He said he needed time to recover, but he would help them fight.

Sa-min carried Mirr to Taesan’s old building. The hellmouth pulsed there like a black heart. He took her stone and merged it into his body.

World in Chaos, Forces Gather

The angels reached the place. A battle broke out between them and Sa-min’s army. Then something worse happened. Sa-min revived four dead angels—the Ox, the Rabbit, the Goat, and the Rooster.

They were once Taesan’s closest team. Now they stood as enemies. Taesan’s hands trembled. They were like siblings to him. He didn’t want to fight them.

But he gave the order anyway. He told everyone to fight them no matter what. His voice cracked as he said it.

Taesan pushed through the chaos. He reached Sa-min. Sa-min smiled. He told Taesan to join him. He said together they could become unstoppable.

More spirits rose behind Sa-min. They crept closer to Taesan. Their whispers echoed across the ruined halls.

The air turned heavy. Taesan’s sword shook in his hand.

Twelve episode 7 explained shows how the story digs into grief and ambition. O-gwi’s wish to rise as an angel made him fall as a demon. The episode lays bare his pain without softening it. It asks if love can survive when someone chooses power over grace.

The war has just begun, but the real fight is inside their hearts.

Editor & Writer’s Analysis: Deconstructing the Narrative

From a storytelling perspective, this episode is a masterclass in payoff. Here’s what makes it work so well:

• The Flashback as a Structural Device: The use of the flashback during O-gwi’s collapse isn’t just exposition; it’s an emotional gut punch. It forces the audience to intimately understand what was lost right before we see the consequences of that loss in the present. This creates powerful empathy for a character who has technically become a villain.

• The Faustian Bargain: O-gwi’s story is a classic Faustian tale—a character makes a deal with a devil (Sa-min) for power (to be an angel’s equal), but at the ultimate cost (his soul, his love). The episode brilliantly subverts this by having O-gwi immediately break the terms of his bargain, showcasing that his love for Mirr is his one remaining shred of humanity. This complexity is what elevates the narrative.

• Symbolism of the Revived Angels: Sa-min’s resurrection of Taesan’s former team is not just a power move; it’s psychological warfare. It weaponizes Taesan’s love and loyalty against him, creating the highest possible stakes. A battle against faceless monsters is simple; a battle against your own grieving family is tragic. This raises the narrative tension exponentially.

• Theme Integration: The core theme of “prayer vs. power” is perfectly illustrated. O-gwi sought power through prayer for grace, but when it didn’t come, he took a darker power. This episode asks the audience: Is the outcome (power) what defines the morality, or is it the method (grace vs. force)?

Why This Matters for Viewers:

Understanding these elements allows you to appreciate the show on a deeper level. It’s not just about “what happens next,” but about the “why” and “how” of the storytelling.

This episode sets up the internal and external conflicts that will define the rest of the series, making the fates of every character feel weighty and significant.
