Rosamunde Pilcher: Solange es dich gibt (2004)

Milly Cohen lives in modest circumstances with her grandmother Cathy and her little brother Kevin. After the death of her parents, she gave up her art studies and works for the antiques dealer Philip Barnes, a handsome but uncouth bachelor. Philip only realizes that Milly has become the pearl of the store when she quits - due to her boss's unfriendliness and her brother's serious illness. Philip doesn't get on well with the new assistants. He realizes that he has fallen in love with Milly. When he tries to win her back, Milly has already accepted her old boyfriend's proposal of marriage.
