In 1998, three tapes containing secrets were accidentally dropped under the sycamore tree, and they missed each other after seventeen years of no contact. When the rusty scratches meet the snow again, what they thought was a coincidence is actually the necessity that someone has been waiting for their whole life - is that "catch me" an illusion, or is it a confession that has been hidden for twenty-six years?
A tape awakens seventeen years of blankness, and a reunion tears apart the unspoken thoughts. With Liu Qiaoyi's enthusiasm, Xiao Yixue's silence, and Lu Jinan's perseverance, the promise under the sycamore tree has already been carved into the annual rings. Each of them hid half of the truth, but when they put it together, they discovered that all the "thoughts of missing out" were "deliberate waiting."
The volunteer list in 2008 caused the three people to scatter to the end of the world; the snowy night in 2024 allowed the old friends to reunite under the tree. The marbles in the hole in the wall, the unsent letters, and the sobs on the tape all say: they have never really gone far apart in the sixteen years they have been apart. But will that choice buried in time bring everything back to the starting point after reunion?
