Bug report, or at least UX report: Apparent softlock on long event.
The only button that does anything (other than bring up a menu with inactive or irrelevant buttons) is Continue, and that tells me I need to pick an option. Eventually, I realize that there's a separate "Continue" option-text behind the menu bar. It's barely visible, and I can't scroll down to it; I have to check the shortcuts and realize you can hide that menu bar, after noticing the text behind a slightly translucent layer. And some other text that is fully opaque.
The best solution would probably be the ability to scroll slightly further down, so you can see Continue without needing to intuit that important gameplay buttons can be hidden behind UI.
Also, said senior brother is referred to as "she" exactly once in this passage. Unless his victim ran away really fast, and my character was distracted by her speed long enough for the senior brother to kick the crap out of me.
