The story wanders between reality and fiction, and Yu, who has a negative and sensitive personality, changes roles in life and on the Internet.
The fates of three men with very different personalities continue to intersect because of her existence.
Yu is a white-collar worker who travels through the reinforced concrete jungle. Her negative personality and a broken love made her self-isolated and self-loathing.
Yu's boss Li Cheng is a young man with a successful career and extraordinary talents. He is experienced and unexpected in living like a fish in water in a translucent society. In his eyes, Yu is the one who has taken off the hypocritical mask, possessing the purest expressions and the most real depression. So he fell in love with her...
Yu's neighbor Ling is a rebellious and interesting junior student with good looks and a bright smile. One summer night, he fell in love with Yu's beautiful and peaceful smile blooming in the arms of another man, and during the contact, he gradually felt that he could no longer extricate himself...
The owner of the coffee shop is a young poet named Bing Hao. He has a refined appearance and a clean and pale smile. Because Yu and Binghao's dead sister had the same name and a similar blank expression, Binghao had inexplicable feelings for this cold and kind girl who liked her coffee...
The three men all cared about this woman who made them feel distressed behind the scenes, but Yu, who lacked trust in others, only gave half of his heart to the netizen "Monochrome Rainbow".
The days pass...
Yu concluded that the monochromatic rainbow standing by his side and looking at him with warm eyes was among the three of them, so he chose a snowy day and said to him: "Let's meet, today!"
