This is a youth story about two-way secret love, regret and salvation. The cheerful hearing-impaired girl Su Xiaoxing spent her entire youth warming up the seemingly lonely genius boy Gu Yechen, but she passed away heartbroken due to a huge misunderstanding and the "disaster" he brought to her. Years later, when she struggled to get out of the shadows, she discovered that the boy from back then, hidden under the cold mask, was a grand confession of deafening silence and a heavy sacrifice that she had never known. A two-way secret love means that both of them are attracted to each other, but they both hide their thoughts in silence, like two lamps separated by fog, both are on, but cannot shine into each other's eyes.
