finding a medical drama with a scene I remember

I remember this scene where the leads were both doctors and they were kissing inside the staff room. However, few people saw that and thought that they were fighting. I distinctly remember that they locked the door from inside and threw stuff here and there. Then the ML pushed her to some table and kissed her. 

I have been trying too hard to think where did this happen, if someone knows do let me know! thanks!
