Both dramas have a boss - employee relationships. In WWSK the FL is the secretary to her boss, having worked for him for 9 years she suddenly resigns stating "personal reasons" as the cause - we then are led to the ML lead trying to convince her to stay and not resign in which she rejects and he cannot fathom this - this is the superficial plot of the story - there is a deeper story plot behind it all that connects the two of them and makes it more meaningful.
In ABP she works in one of the "food departments" (they create convenient food and flavors that compliment that can be frozen and re-heated and eaten - that's what I understood about it). She hides her identity from her boss, as she met him in disguise previously on a blind date, she was forced to go on the date by her best friend (her best friend was actually the one that was supposed to go on the date) - now she works at the same company as her CEO - hence the fun and drama ensues.

Both FL's are the secretaries to the ML's and the ML's seem distant and indifferent initially but grow to care and protect FL's. Similar in the sense that both have a boss - employee relationships in which the romances revolve around.
