The full story
Chapter 1: A King’s Wrath
Chapter 1 opens in a city swallowed by a monster tower, where Do-Jin, the reluctant shut-in can no longer ignore the storm gathering on the horizon. What begins as a quiet morning turns tense the moment word arrives that a masked envoy has crossed into forbidden territory.
Do-Jin, the reluctant shut-in draws on a fortress-bound ability tied to his own home, and for the first time the true scale of that gift becomes clear. Those who once dismissed the hero as ordinary are forced to reconsider — power like this does not appear by accident, and everyone can feel that the balance has shifted.
Standing in the way is the tower’s floor bosses closing in block by block, whose ambitions have only grown sharper. Their confrontation is less about brute force and more about wills: two people who understand exactly what the other is willing to sacrifice. By the final page, a line has been drawn that cannot be uncrossed.
Beneath the action runs the thread that has driven the hero from the start — to defend his sanctuary without ever losing himself. This chapter pushes that goal one hard step closer, but the cost is real: an alliance frays, a secret surfaces, and the next chapter is certain to change everything.
