Konyakusha wa Dekiai no Furi

For the sake of her impoverished family, Rachiel, a member of the Jaharry family, plans a political marriage with Fahad, the second son of the Aurecia family, who has good looks, good family and financial power. When she asks him to marry her, he unexpectedly says yes! Rachiel, who is not good at romance, tries to show off her flirtatious side in front of everyone, but is always being pushed around by Fahad.
