Su Yunjin had not signed an exclusive deal to sell only to Fuman Building at first, so now, she likewise would not sign such a contract with Young Master Chu.
Su Yunjin planned to open her own wine shop. If she sold exclusively to one establishment, how could she run her own shop? Wouldn't that become something solely for Young Master Chu's use?
Of course, Su Yunjin would not agree.
Furthermore, she had already agreed to continuously supply fruit wine to Fuman Building. If she were to sign such a contract with Young Master Chu now, wouldn't that be breaching her agreement with Fuman Building? Su Yunjin absolutely would not agree to such a detrimental and self-harming act. Originally, repeatedly rejecting the manager had already made things awkward for everyone; if she were to behave unscrupulously regarding the fruit wine deal now, her cooperation with Fuman Building would likely be over.
