Three stories--first is the yakuza heir and his body guard, second is the company president and the employee he gets to help him break up with a girlfriend (and they end up together), third is the 1st Yakuza heir's friend and the pet store employee he falls in love with.

Series of multiples with a doppelganger of a prince and his bodyguard. One story was childhood friends who meet again and get together. One story was a priest and parliament member who get together. (Loved this one. Made me almost cry.) One was a CEO and a driver. Final short is an after story with the doppelganger/bodyguard and one with the (former) prince and his caretaker.
Omamorishimasu, Dokomademo
I'm... not sure if I like this or not. I like most of the story, but the ending was awfully ambiguous. I would have liked a more solid ending. Akira DOES love Chihiro but he didn't admit it even by the little extra in the end. Plenty of "Badumps" but nothing else. Stick with the other Junko stories.
