While restoring an old book from the Republic of China, cultural relic restorer Lin Xi accidentally uncovered a dusty past - an unfinished score called "The Temperature of Fingertips" and a love that ended abruptly in the flames of war.
In order to complete the restoration, she found cellist Gu Yan. This talented musician with a cold appearance is actually the descendant of the protagonist of that past incident. When the fingertips touch the yellowed piano score, and when the melodious sound of the piano sounds, two souls from different eras create a wonderful resonance through music.
They followed the clues of history and pieced together the truth of the year bit by bit. In the process, Lin Xi not only restored the cultural relics, but also healed the scars deep in Gu Yan's heart. A pursuit across time and space, a modern love song played among daily necessities, rice, oil and salt, quietly kicked off.
