Every shared blueprint is a battlefield; every argument crackles with forbidden chemistry.</p><p>When a sudden winter downpour forces them under <strong>one shared umbrella</strong> the six-centimeter personal space rule Ji-soo enforces is broken and the line between professional antagonism and desperate electric attraction starts to melt away. But as they begin to realize their opposing minds form a perfect terrifying synergy an unseen enemy-a <strong>Ghost Architect</strong> known only as 'The Catalyst'-begins a campaign of sabotage targeting Tae-joon's work and threatening to dismantle not just the project but the vulnerable foundations of their newly built trust.</p><p>Can they survive the cold reality of betrayal or will their fragile architectural romance collapse under the pressure of a Christmas deadline? <strong>The only structure more at risk than the market is the one they're desperately trying not to build: a life together.</strong></p>
