In the seventeen-year-old library, the fingertips of two teenagers accidentally touched.
One is an abandoned orphan, and the other is an heir bound by the family. They made a promise no one knew between the pages of the book.
Seven years later, we met again in the clinic of the gland specialist.
He is a calm and self-possessed doctor, and he is an officer patient with pheromone disorder and neck ring overload. The medical records read: Cause - long-term depression.
The heart lock that has been rusting for seven years has finally been waiting for the key to return to its place.
Every diagnosis and treatment traces back to the unfinished agreement from that year, and every pheromone confrontation is a late test.
He wants to repair his disordered glands, but discovers that he is the source of his depression.
He chose the most painful treatment plan just so that he could look at the people who had no time to say goodbye in an honest way.
Can this rusty heart lock be reopened by the key from back then?
They are each other's only lock and key.
Concept: Rusty locks hide old promises, and they will return with the key after seven years
