I think the one at the end of the chapter 2, the girl focus with the umbrella, is a different girl, i think she is might be Hoshino Mirai, she is absent on the start of chapter 2 and then showed up on chapter 3 so it connectsThat can't be Oono's daughter right? When we saw her at the end of chp 2 she had black hair.
I think this is going great. I know people have been wanting to see the games but ultimately the original High Score Girl was a love story. It heavily feature games, but it became less and less of a feature as the story progressed.
Instead of repeating a love story, it seems the story is going to show that games can mean different things for different people. Escapism from different situations. People with different backgrounds who can unite over the love of games.
