Su Wan and Lin Chen have been in love for seven years. After she unexpectedly becomes pregnant, the Lin family deliberately humiliates her with a bride price of just 2.8 yuan. They even switch her folic acid supplements, hoping to use the baby to manipulate her. Su Wan pretends to give in, but at the wedding, she publicly calls off the marriage and exposes the Lin family's schemes. Lin Chen maxes out the credit card Su Wan gave him, racks up a massive debt, and eventually falls into Xiao Li's revenge trap.
