Just an assumption (I’ll update the post if it changes)

The game culture is a little weak although better than some. But the focus of the show for me is the sister’s guilt because of her dependency on her family. She’s quite annoying until they talk it out properly towards the end. All the characters make sense to me in the way they are supportive and caring, there’s even a bit of kickback against toxic idol culture, and the gaming storyline connects everything nicely.
