Excuse me, the balcony of the living room faces east. Will it be dark without sunshine?

Now houses generally consider the north-south orientation, one is natural ventilation and the other is sunshine. Generally, the master bedroom and living room are best facing south. But if the living room can't face south, there is not much difference between east and west, north and south, and it must be darker than south. As long as it's not Lucy, Xiyin keeps the room hot at night.
