Hi! I want to reread a chinese novel (if I’m not wrong) about a rich teenage girl who fell in love with her temporary bodyguard. But her bodyguard has a girlfriend and rejected her. After a few years her bodyguard become a successful CEO in the states (if I’m not wrong) and when her bodyguard goes back to his hometown, he starts to look out for her and eventually found her. The teenage girl become a librarian in the future because her grandfather doesn’t want her to become spoilt like her mother. I hope someone can find out the title. Thanks in advance!
