Ten years of secret love turned into the tip of a pen to heal lines. Yuanqi illustrator Shen Shuyi hides surgeon Han Mingseul in every cartoon, recording his gentle eyebrows and cold outlines with a brush, but never dares to express his feelings. When the family's pressure to get married came, Han Mingse asked her to pretend to be a couple in order to deal with her elders. This relationship that started with a contract quietly opened up the dust-laden feelings.
The stern doctor on the operating table anonymously confides her frustrations in her comic comment section late at night; the protective memory of her girlhood is intertwined with the sweet daily life of getting along day and night. Shen Shuyi's secret love hidden behind the painting was unexpectedly exposed, and Han Mingse read between the lines the deep love of ten years. From young heartbeat to clumsy approach, from misunderstandings to frankness, when the layers of vest fall off, this fake love will eventually become the brightest moonlight in each other's lives.
