ISO

With the ISO 5000, it made the picture visible but a little blurry. In the picture with ISO 50, you can't even see my partner. Then, with the flash, you can clearly see the person and everything else around them. However, it made the photo really washed out and you can't see the effect of the light. Changing the ISO can allow you to get the perfect picture you want. If you want to emphasize the lighting of the room, you can do it by changing the setting of the ISO.
