Okay, I just went and translated the text and hex decimal text. "am i okay" and "goodbye". I haven't done this previously with other text but I doubt it was important...
You may want to have a hex translator bookmarked, but you might also want to look up the event on the wiki. Not sure how easy it is to find the event name with autovn, guide mod makes it easy enough with normal play.
The wiki has most of the translations done, even for messages that only appear for one frame
Maya claims the tsundere role is already taken... but whom tho? Yumi? I highly doubt it. I only see one potential candidate and that's Makoto but when you look at Makoto's behavior, you also realize that she's also one of the few girls who are that interested in him, so that just kinda... defeats the whole purpose of the tsundere role too. So that really only leaves Yumi and Maya and I don't see any implication that Yumi is secretly pretending not to like him. Maya is the only one whose shown signs so far between them. It would have helped tremendously if the dev nudged in an example of who Maya was referring to with that tsundere claim. Anyone knows?
Definitely Yumi. You might not have seen enough Yumi yet between start of the game and Autovn. But Sensei does make a point that she blushes a lot when they argue. And she lets Sensei get away with a lot for someone she wants to die.
Just like Maya
Makoto just hasn't had enough screen time to bloom. She's quite the opposite after a certain point.
Just figured out you can see the pictures the mc takes, even send them back to the person with a comment.
You'll be sent some unprompted as you progress, but events will happen like Makoto's Dildo and if you pay attention you can get some extra phone lore immediately after the event ends and you reach the next menu / event.
