A seaside guesthouse faces a night of approaching storms. Su Tang, Lu Heng, and Xu Zhou check every corner of the guesthouse for hidden hazards, one by one. From the front hall's floor-to-ceiling windows to the guest room window frames to the kitchen prep area, they carefully adjust door and window latches, seal weatherstripping, and organize the flow of foot traffic. Each change is made in small steps, retested repeatedly to avoid creating new problems. As the rain intensifies, the roof drainage shows signs of clogging. The three put on protective gear and climb onto the rooftop platform, clearing fallen leaves from the drainage ditches by hand. Night and sea breeze shroud the entire guesthouse as they safeguard its reception safety with a rigorous, practical approach, quietly awaiting the dawn after the storm.
