They used to be each other's secrets hidden deep in their hearts, even approaching each other with cautious joy.
An unexpected misunderstanding turned that unspoken love into years of silence and miss.
Later, when they met again, they thought they were reunited, but they didn't know that the rift had already been deeply rooted.
They test, approach, and push away, repeatedly pulled between love and hate, obviously they still care, but they insist on stabbing each other.
Later, he married someone else, but she kept her memories and never married.
It turns out that there is some heartbeat, but once you miss it, it will last a lifetime.
From now on, the mountains are high and the rivers are far away, and there is no time to return, only the uncertainty remains.
Concept: - A broken mirror cannot be reunited: Reunion is not redemption, rifts cannot be repaired, and some relationships cannot return to the beginning after all.
