Boss ga Sazuketa Takaramono

Amie is a designer and a member of the family that owns a huge jewelry company. At her cousin's wedding party, she meets a man with whom she falls passionately in love and spends the night together. The next day, however, she discovers his true identity. He is Preston, the new CEO of her company. By order of her grandmother, who has absolute power, she and Preston travel together to a new product launch. On the plane, they reach an agreement to keep their relationship strictly business, but it's hard for them to spend day and night together when their body gets hot just by looking into each other's eyes.
