Tameiki no Gogo

Alex hates hearing that she gets preferential treatment as the daughter of the CEO of a top department store, so works harder than anyone else. She is incensed by Jack, the rep of an ad agency who scuffily dressed, visits regarding a new ad and has the nerve to try to seduce Alex! There is no way this kinda guy can work properly...but seeing Jack's presentation the next day, Clara can't take her eyes off him...
