Raviel Sutton has a serious problem: her younger brother, Edwin, loves her a little too much. In her previous life, his obsession with making her the ruler of the continent led to her becoming Empress, only for her to die tragically from sheer exhaustion. Now, having regressed to the past, Raviel hopes for a quieter life, but Edwin—aka "the lunatic"—has already maneuvered her back onto the throne. Realizing she can't escape her royal duties, Raviel hatches a survival plan: marry a pushover husband who can handle the heavy lifting of ruling the empire so she can finally rest.
However, her brother’s matchmaking skills are as chaotic as his personality. Instead of a docile puppet, Edwin manipulates the situation to ensure she marries Duke Haven Derhardt, the infamous "Monster of the North." Far from being a pushover, Haven is a powerful figure with his own secrets, yet he seems suspiciously compatible with Raviel’s unhinged brother. As the three of them form an unlikely power trio, Raviel discovers that her new husband might be the only one capable of standing by her side.
Brother Knows Best is a refreshing take on the regression romance genre, blending hilarious character dynamics with genuine political stakes. As Raviel battles assassination attempts and navigates the treacherous waters of the imperial court, she must also guard the secret of her return. But with a husband who is more than he seems and a brother willing to burn the world down for her, Raviel’s second chance at life promises to be anything but boring.
