Yeah mixed race couple! But, Booo stereotypes lol. This has been on my favs list forever, re-read whenever I comeback to yaoi after a break. Aside from the refreshing ethnic mix, Sword and Sen have a real 'Bonnie and Clyde' vibe. They are more dangerous together than apart. It raises the usual "possessive lover" trope to a new level. They are truly a tough couple. I love how they are both so dangerous yet gentle to each other,
