Boss x Secretary

Hey guys I would really appreciate it if someone helps me out to look for this yaoi manga which about a secretary who used to be kinda "raped" all the time by his boss then when the boss dies he ends up with the son... and they actually fell in love.. cuz the son knew that his father was a bad guy using the secretary for his own satisfaction since he helped him once to save his father ( the secretary's dad) by paying the bills of the hospital or something like that...
