They are lovers separated by time.
A startling glimpse on the subway, a gentle whisper in the projection room, and a sudden catastrophe, freezing the first meeting into an indefinite parting.
The boy in the old time and space guarded an empty city and a love letter and survived five years of loneliness; the girl in the new time and space, carrying a heartbeat and regret, traveled backwards through the years to find an old relationship.
The barriers of time and space are tight, the time paradox is unsolvable, snooping will backfire, and it is risky to go there.
Cuteness is the most fearless, and persistence can overcome all difficulties.
When he feels the gaze that transcends time, when she rushes towards the tenderness hidden in the past.
The five-year time difference has completely disappeared, and all regrets have been redeemed.
It turns out that the best love of time is never passive waiting, but that I cross time just to embrace you.
