Yay, I'm so glad you're excited!
As the narrator, I really look forward to those options! This is a game of choices and relationships after all, so it isn't a spoiler to say that there is more than one upcoming decision to spend time with the Younger.

The only problem is that the Younger Twin is not overly keen on spending a great amount of time with you... yet.
So probably not in the first chapter, although these edits do include one more dialogue moment with U, near the end, if you choose that option. It's not a full scene but I enjoyed adding a few more paragraphs, and hopefully you enjoy reading them if you play the updated demo!
