Yes it is in past tense. And the excerpt if fine to me, and I was going confirms it is in past, they're all the thoughts of the protagonist ( narrator ) but there's difference between narration and inner thoughts like ( ...I was walking home and I ran into some guy he insulted my , '' Why did you insult me ? '' The guy : '' I wanted to '' , This's just a fool I'll just ignore him or so I thought but that's not how it passed...) you see the italic sentence that's a inner thought from when the event was occurring the rest is the narration is the current thought of the author since he's narrating.. but in higurashi there's nor italic they all are in bold one sometime cannot know if they're the thoughts of the protagonist at the time like the dialogues basically or they're narration to me it's wrong to use second conditional to narrate about the past unless it's an inner thought from past and that's what I want to know.
