Shoushin no Honeymoon

Clara has worked for her boss, the smart and handsome Zack, for seven years, but she only realized she was in love with him when he announced he was engaged. She did her best to suppress her feelings for him and help him get ready for the wedding, but when the bride didn't show, it was called off. Yet Zack doesn't seem particularly upset. He says the marriage was just a business tactic. Clara is already perplexed, but then Zack says something even more unexpected. He asks her to go on the honeymoon with him in his bride's place!
