Jian Yao, the sister next door who was always with her when she was a child, turned into an elite member of the Mingde University student union ten years later and unexpectedly reunited with Lin Sheng, who had just entered the campus. A deeply buried childhood confession letter reveals the secret of a secret love that Jian Yao has held back for ten years; a sudden crisis in a school anniversary promotional video allows the two to rekindle their bond in the interplay of light and shadow. When rumors and family burdens ensue, they take off their armor to the sound of piano on a rainy night and face the lonely years behind depressive drugs. From ignorant guardianship to two-way love, this time-traveling couple used their courage to crush worldly prejudices and made a promise for the rest of their lives with a new "time capsule" - no matter how the stars change, only love and youthful heartbeat will never fade.
