Any stories where the male lead won't hesitate to use physical force against someone if needed except the female lead who he loved? Like maybe she's friendly with this other guy who likes her and he beats the crap out of the guy for trying something? He's super protective over her. Eventually she begins to hate how he's acting so he changes his way and they reconcile because she loves him so much.
