This is what I read from previous posts.
Rita is dating Mart, he's cop and not your romantic type.
Rita wants to get marry so she tries to get Mart jealous in order for him to propose to her.
Noon is Rita's bbf and is the reasonable in their relationship.
She works for a company that has gone under and will be taken over by new management.
The new management team and her new boss happens to be Rome.
Noon and Rome have a clashing personalities when they first meet and they constantly bicker over stupid things.
Eventually, Rome and Noon will fall for each other. You know how lakorn goes.
