Emergency department backbone Su Tingwan and group president Shen Qi'an, following their elders' old agreement, signed a two-year agreed marriage, agreeing to a hidden marriage and non-interference, solely to pacify their families. The two moved under the same roof, growing closer amidst emergency life-and-death routines and family conflicts. Rebellious sister-in-law Shen Qi'nian, guided by Su Tingwan, witnessed the various states of the mortal world and came to a sudden realization. The two broke through the shackles of the contract to confirm their feelings, returning to the countryside to visit Su Tingwan's grandmother. Su Tingwan participated in the National First Aid Competition; after the post-competition celebration banquet, drunkenness exposed their couple identity, and after experiencing gossip storms, they rushed towards each other in both directions and harvested true love.
