I enjoy this series, but it's so roundabout and complicated like a Chinese stepsister webnovel. Jayna could easily shut Angela out of high society without going through all this effort of spreading rumors, hosting a party for her, doing tournament shenanigans, etc.
She doesn't even have to let Angela live in their house. She could have found a small cottage for her in town while her father was away, and just presented a fait accompli afterwards. Sheesh! š
