Because while you are welcome to interpret it as you will, there is an obvious scenario of nasty female fighting over something with FL and I wasn't convinced After the Show Ends fits the general vibe. You could take the clip to mean they are fighting over anything, person, place, thing, job, status, you name it. 2 females fighting over a male is a given in most dramas. If one told the other they no longer wanted him and the other could have him, happy to allow it.
Sorry, not making myself clear. Since it has been a while, we can include male leads letting go of rubbish as well.
