The Seventies Background Extra Gets Together with the Villainous Big Shot

【Transmigrate into a book + villain + sweet romance】 Tong Lele has transmigrated into a book!!! She becomes the male lead's fiancée, who dies young in a rebirth-era novel, a character who barely qualifies as part of the background. Looking at the beautiful, mature heroine, Tong Lele just wants the male lead to get as far away as possible. He hasn't even dealt with his awful family, and he still wants to go after her! Hmph, how full of himself! Before Tong Lele can begin her campaign to break up the canon couple, a System suddenly appears and tells her she has only one week to live. If she wants to keep living, she has to complete missions! Tong Lele throws her head back and sighs. Why? Can't I just live as a happy couch potato? At last, I have a family who cares about me. No choice. Staying alive comes first. Looking at the handsome young man who saved her, she asks the System uncertainly, “Are you sure he's the big villain?” “Yes. Host, please complete the one-minute eye-contact mission...” Reluctantly but wholeheartedly, Tong Lele sets out on the path of completing missions to earn more life points, and never turns back. At first, Jin Xiangnan is simply curious about why her life points keep going up. Later, as he looks at the petite beauty in his arms, he can't help being grateful for that initial curiosity.
