The scalpel can mend the heart, but it cannot mend the memory. Until the moment he appeared.
Lu Zhi'an, a top cardiac surgeon, is calm and self-possessed, and never misses a beat on the operating table. There is a hole hidden in his heart for twelve years - his twin brother Lu Zhining mysteriously disappeared when he was a teenager, leaving only an old suitcase.
On a rainy night, an amnesia patient named Song Yan was sent to the emergency room.
He suffers from a rare case of retrograde amnesia, and his past is completely blank except for an old, unexplained scar on his heart.
When Song Yan subconsciously pressed his heart and reported the accurate heart rate, Lu Zhi'an's heart skipped a beat - that movement and that back view were very similar to his brother who had disappeared for twelve years.
