Two beauties from the Western Regions accidentally enter the wrong households in their bridal sedan chairs. One falls straight into Prince Ning's arms, while the other becomes an honored guest of Prince Chen. Their false princess identities hang over them like swords poised above their heads, and to make matters worse, both princes are more troublesome than the other. Luo Qi suspects Pei Qingyan has discovered something, but all he does is gently wipe the pastry crumbs from the corner of her mouth. Luo Shan waits for Pei Qingci to expose her, but instead, he smiles and slides half a jade pendant toward her. The Crown Prince's spies have already infiltrated the princely residences, and urgent military reports from the border arrive day and night. How much longer can the sisters keep up their deception? Or perhaps the princes never intended to expose them in the first place.
