Dominating, unhinged older brother VS a sister in sheep's clothing
Mu Changfeng is the eldest son of Marquis Mu, and Mu Yunhui is the youngest daughter of the Mu family. (They aren't related by blood.)
In their early years, the siblings guarded a frontier city in the northwest. Mu Changfeng often dragged his heavy greatsword behind him, striding with a don't-mess-with-me swagger and carving deep marks in the gravel. Any man who coveted his sister was scared out of his wits.
Later, Mu Changfeng became a famous general of the northwest, but he still liked dragging his greatsword behind him, striding with a don't-mess-with-me swagger and scaring out of their wits every man who coveted his sister.
Later still, the Mu family raised an army in the midst of chaos and conquered the realm. Mu Changfeng became the all-conquering madman... and her Imperial Brother.
Well, my brother is going to be emperor. And of course, the thing he loves most, aside from the throne, is me.
And me... I'm actually someone who plans to defy heaven, too.
This novel also has the literary title "The Wind Goes, But the Clouds Do Not Return." In keeping with my usual style, it's sweet with angst, angsty with slapstick, and slapstick with madness.
Theme: You only win if you dare to fight.
