Millions of Bitter-Sweet Kisses

Maho with her strong older-sister-like personality and carefree Atsushi are dating, but it's a secret from their company! I'm strong and responsible at work but I want to be spoiled at home! The insensitive boyfriend just doesn't understand that... on top of that a cute girl that wants to steal him away!? Lots of fighting but lots of making up! The path to marriage is still far away for this modern day couple!!
