Dressed as the Male Protagonist's First Love in the 1970S

(Under deposit, updated in September^o^) Su Xiuxiu never imagined that one day she would be in a book, She became the first love who has the same name as her in the original book and only exists in the memory of the male protagonist. Forget it, what's even more tragic is that we still have to live in the special 1970s. The only consolation is that when you come through, you come with a system. Unexpectedly, the only purpose of its existence is to urge her to obtain the happiness value of the male protagonist. Fortunately, the mall was opened after updating the system, but what are these? ! ! A good helper in farming, a little expert in the kitchen... Can I apply to change the system again?
