In the windy summer night at Jiangcheng University, Chu Yining, a gentle and sober student from the Chinese Language Department, met Fu Jinzhi, a cold and domineering academic from the Computer Department. An unexpected encounter led Fu Jinzhi, who was cold on the outside but hot on the inside, to bring Chu Yining into his exclusive protective circle. He protected his wife domineeringly and never allowed her to be wronged in the slightest. From the silent companionship in the library, to the guardianship after evening self-study, to the affectionate confession in both directions, the two people were sweet and had no misunderstandings throughout the process, supporting each other academically and growing together in love. At the same time, the heroine's best friend Yin Chuntian and the hero's roommate Qi Mingyu also started to have a sweet love for each other, protecting their wives in both directions, and the sweetness was full. The four of them walked side by side, were admitted to graduate school together, and stayed with each other from the youthful campus to every year. They spent their lives interpreting their preference and perseverance, pampering them throughout the process, and living up to their heart's desire.
