Yun Guantai × Yun Guanyan
A cheerful, sunny, sweet-yet-scheming girl who flirts without realizing it × A mature, dependable, sister-obsessed boss with possessive tendencies gone bad
The protagonist lives for a laugh, but she's also a laugh-seeker who's been badly played. The more smug she is at first, the worse things get for her later. This story is all about indiscriminate damage. It's a new author's first book, born from a late-night bout of insomnia and delirium, with a wildly imaginative premise.
A few warnings: unlike typical matriarchal romances, this is not recommended for readers looking for a story full of romance between a man and a woman. The orientations are a complete mishmash, and everyone's a villain. There are lots of details and Easter eggs. If you can't stand seeing the protagonist get played, drop the book. We never have to meet again.
