Review Detail of X_X_I in The Substitute Madam Amazes the World Once More

This is based on 40 chapters. There's nothing new about this plot but at least FL can handle herself without relying on the ML too much. She has many skills that are slowly appearing when needed. Though their engagement was discussed & neither were in favor of it (but they also weren't strongly against it), their relationship is developing quite nicely. FL is willing to help ML, & vice versa.
