ML & FL get together early on, and then others causes problems for them

Looking for shows where the ML & FL start dating early on (within the first 5 episodes and no contract-type relationship, real dating), and then it deals with the ups and downs of their relationship. Will take people trying to sabotage them, some asshole SML trying to steal the FL away from the ML and maybe succeeds due to misunderstandings. Stuff like that. As long as its a happy ending where the get back together.

• Fight For My Way | Don't remember exactly when they start dating, but it's pretty early on.
• Lawless Attorney | No one's really getting in the way of their relationship. Rather they are both focused on ensuring justice.
• Let Me Introduce Her | They start dating pretty fast but things happen that force them apart for a good while. 
• Mask | Leads get married almost right away, but they have enemies all around.
