Amid the concrete-and-steel jungle of the city, Su Qingyuan and Lu Zeyan are the architecture firm’s most in-sync “comrades-in-arms,” yet also the most distant of coworkers. Over three years of working together, they have sparked countless design ideas during late-night overtime and stood shoulder to shoulder against difficult clients on demanding projects, all while keeping a polite distance.

In the cramped space, their body heat and racing heartbeats become impossible to ignore. It turns out that the care they had cloaked in “professionalism” had long been a hint of love. When workplace rationality meets a tide of emotion, can they break through the barriers between them and turn their slow-blooming office romance into a match made in heaven?
