His father's mistress... Lacey Tyrell's relationship with Sir Clive Parrish was entirely innocent. The only people who didn't believe that were Clive's sexy stepson, Jon, and the journalists who were after Lacey's blood... Jon Parrish was determined to save his stepfather from further scandal no matter what it took. He had stolen Lacey away to his remote hideaway to keep her out of trouble. But there was just one problem. Jon had taken one look at blond, doe-eyed and beautiful Lacey and decided she was certainly mistress material--his own! [Taken from FictionDB]

From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): This 4-koma manga follows the daily life of Natsuno Yoko, a tiny woman with a big personality. Natsuno has had a very small body and voice since birth, and that's still the case when she's grown up and working as an office lady. She works very hard, though, and has a memorable attitude and way of going about her work. [tethysdust]
