At the age of 13, we declared war upon first meeting! Xiang Nuan moved into Zhou's house, and in front of 16-year-old Zhou Yu, he tore into pieces the 23-article "Family Covenant" written by him. With a flick of the red pen, he wrote the 24th article: "The final interpretation belongs to me!" The fate of this pair of childhood sweethearts officially kicked off with tit-for-tat exchanges. When he was 16 years old, he forced her to tidy up her room using "star standards", then secretly photographed the starry sky graffiti she painted all over the corridor and locked it in an encrypted photo album; when she was 18 years old, he gave her a top-of-the-line computer and asked her to "use her future to pay off her debts", but before she insisted on living alone, he gave her a survival test paper full of "difficulties", which in fact secretly taught her how to deal with the dangers of the world. When they meet again in the workplace, she is a newcomer who has made it through with her strength, and he is the extremely cold and scumbag Mr. Zhou - the "death penalty project" throws her face out and calls her a "trash" in public. The "fights" between the two escalate to the workplace battlefield on a daily basis. Xiang Nuan thought that the past warmth was all an illusion, until the USB flash drive on his desk revealed the truth: it contained in-depth analysis of project failure cases, the Morse code of "hold on" hidden in the coffee cup cover, and his silent guardianship of using his one-year promotion opportunity to take the blame for her. Not to be outdone, she "revenges" him by cooking Zheer root and forcing him to accompany him to watch mindless sweet pet dramas. However, when he had a stomachache, she scolded him for "bringing it on to you" while she cooked stomach-nourishing porridge. From the mutual graffiti in the youth corridor to the tit-for-tat confrontation in the workplace conference room, they found out each other's softness through funny bickering and supported each other's growth in "fighting" confrontations. A two-way redemption that started with mutual quarrels, fun, mutual feelings, and finally staying together. The tenderness hidden in the harshness has always been their affectionate password.
