No offence but I find the screen space thing nonsense tbh. The main lead is and should always be the story.
If you see Shaadi Mubarak (it's the only example I give these days because that's the only show I am watching), the male lead was nowhere to be seen in today's episode, and he probably won't be there in tomorrow's episode as well but the episode was so so good because the focus was the story.
What a joke to say leads don't get ss when misti hogs ss everyday.We can say Abir have less ss compare to Misti. Kuhu akele deewaro se baat nahi karti.Misti have ss with everyone even with her new found bff😏
