Qing Chenlu has been secretly in love with Lu Siheng for seven years.
From high school to college, from college to the workplace, she hid this feeling in every heartbeat that passed by, in every peek that pretended to be casual, and in the words in the late-night memo that would never be sent.
She quietly compiled all the project information he needed for three years behind his back, but never left her name on the report.
Seven years later, when the airborne Lu Siheng became her immediate boss, when she was forced to become a "shield" between him and his new love, and when she thought that this secret love would eventually end in vain, she discovered that during those years, he was also approaching her cautiously in his own way.
Concept: The sweetest secret love in the world is not the watchfulness of one person, but the tacit understanding between two people.
