Day three at the western wall service passage under smoke-darkened morning light.

Tabi and Ho confirm the ugly trade-off before the day-three binding.

Tabi performs the day-three binding on the western service passage.

The service passage binding is tested and accepted without celebration.

The night before day four collapses into an early assault.

The steppe warband launches an early attack while Sun-Beol scrambles awake.

The inner sally-port is introduced as an urgent day-four target.

Madam Ho warns Tabi about hidden reinforcement, but battlefield urgency pushes him forward.

Tabi binds the inner sally-port with an incomplete understanding of its structure.

The ram strike reaches the sally-port and tests the rushed clause.

The hidden second frame contradicts Tabi’s clause and the binding begins to fail.

The inner sally-port fails open under the ram strike.

Two squads are trapped in the passage after the failure.

The attack is contained, but Tabi sees the human cost of his failed clause.

The survivors expect Sang Eo-jin to punish Tabi.

Sang gives Tabi an order instead of punishment.

After the failure, Tabi returns to the corridor and learns the exact reason his clause failed.

Day five’s binding holds, but Tabi has changed how he works.

That night, Tabi is alone with his guilt and the wrapped kitchen door.

Madam Ho visits Tabi after curfew, not to comfort him but to tell him history.

Madam Ho tells Tabi that she knew of his mother before Sun-Beol.

Ho describes Yeon’s refusal to bind a bedchamber door to trap a girl.

Ho explains the scandal was buried and the captain rose through the ranks.

Ho confirms the old story names Sang Eo-jin, leaving Tabi with sharper hatred and no certainty beyond the rumor.
