Lin Shen, the owner of a psychological clinic, was trapped on the day his ex-girlfriend Su Xiao committed suicide. In the seventh reincarnation, he accidentally put on her headphones and was able to sneak into the memory fragments of the last days of her life. In the countdown-like seven-day cycle, he is no longer a savior, but a silent witness, witnessing the workplace strife, family blood-sucking, and loneliness that she has never told under her smile. Every dive is a dig deep into the wound. This time, he no longer tries to physically block her, but wants to complete a dialogue that spans life and death in the last "echo" before she is completely broken, and use true understanding to open her desperate heart.
