The female protagonist is a Muggle male protagonist. The early pull was great, but unfortunately in the later stages the heroine became a bit like an annoying mother, without her own life or hobbies, just revolving around her son.
Surprisingly, this is one of my favorites among U of T fans. This novel is not as well-known as other novels, but the heroine is so charming. A Slytherin sister who is very strategic, scheming, and always knows what she should do. The interaction with SS is also very tense. (I'm not Si Chu but this book is very good)
