This is a story about "unexpected encounter". In a blind date forced by her mother, advertising planner Lin Yue unexpectedly reunited with architect Su Ran, whom she had a romantic relationship with three years ago. From the awkward first meeting in the wind on a summer night, to a cup of hot cocoa on an overtime night, to the slow-motion time in the art gallery, two people with gentle personalities slowly get closer to each other through inadvertent interactions. There is no grand plot, only the tenderness hidden in the details - remembering the old hair tie you lost, knowing that you are afraid of the cold air conditioner, and being willing to waste an afternoon with you in the art exhibition. Their heartbeats are like warm water brewing tea, half a beat, but slowly settling into the most comfortable temperature over time.
