Zhou Dongtian is a wild fungus appraiser at the Provincial Academy of Agricultural Sciences. People call her the "human microscope". She could sit in front of a microscope all day but could not survive three minutes in a social situation. His father disappeared in the mountains, leaving behind a culture collection center that was on the verge of closing down. She thought she would only deal with fungi in her life until she met Ji Shihan in court.
The CEO of Hanmang Biotechnology has a paranoid desire for control hidden under his gentle and jade-like skin. A case involving the identification of a toadstool worth tens of millions led to a confrontation between two people in court. She won the lawsuit and his company's stock price dropped to its lowest limit. They were supposed to stay away from each other forever, but grandma's culture center was forced to a dead end by debt.
Ji Shihan handed over a contract marriage: for two years, he would help her pay off her debts, and she would regularly provide bacterial samples and act as Mrs. Ji. Everyone gets what they need without emotion. Zhou Dongtian signed, but added one additional thing - accompany her to the mountains to collect fungi once a week. No one knew that she wanted to see clearly the birthmark on his wrist that was exactly the same as in her father's notes.
From mutual dislike to being in the same room late at night, from the fragrance of fungus to help you sleep to searching for fungi from thousands of miles away. A woman who can understand fungi under a microscope but cannot understand people's hearts, and a man who is comfortable in the world of capital but cannot cure insomnia. When the fake marriage grows the roots of true love, and when the truth involves the deep hatred between the parents, can this relationship entangled with mycelium withstand uprooting?
Marriage is symbiosis, not parasitism. Some feelings are like mycelium, invisible, but already embedded in the bones and blood.
