Using quirky ideas and milk tea expertise, she hooks up with the Seventh Prince Xiao Heng, who is feigning illness and weakness. From mutual probing to falling for each other, the two jointly defeat the repeated framed charges by the Noble Consort and Su Rou, turning the milk tea shop into an imperial-grade chain. She follows her husband to the frontier border, using milk tea to stabilize army morale and drive back enemy troops, helping Xiao Heng heavily defeat Beidi, and ultimately counterattacking to become a first-rank commanded princess consort, reaping success in both career and love.
