Okay, time for another long post! (Once again, apologies to the constant notes.)
Just finished Hikaru's route and got his best ending. Not my most favorite guy of the bunch (it's unfortunate, I've never been too big on tsunderes), but I enjoyed how naughty Haato is around him. (Quick question: are each guy's routes written by different people? Or am I just reading too much into the fact that Haato drops the f-bomb quite a few times in Hikaru's route, whereas he never actually swears on the other guys' routes--or at least the ones I've been on)?
You guys sure weren't kidding when you said that using the cheats takes away from the gaming experience. On one hand, it's nice not to keep worrying over money and stats. On the other, there are just so many empty days. Now that I have Hikaru's Fame cheat (and Shuu's Money cheat), I technically don't have anything to worry about except romancing a guy. That said, the skipping function will probably help a lot in this regard. Hope to see it fixed soon! ^^
Now onto a few notes: [SPOILERS AHEAD! BEWARE!]
(1) This error appeared after "I'll be glad to" > "Let's go out" > "Yup! Let's go to the shopping mall or the cinema" option. 
(2) After you choose to confess and your relationship status changes from Crush to Lovers (right after the dialogue box that reminds you to keep spending weekdays with Hikaru), Hikaru's sprite shows up again and goes "Gah! Forget about it" for some reason.
(3) You're unable to reject Hikaru's confession; an error keeps appearing if you do. (Ngl that made me laugh; I couldn't help but think "of course Hikaru won't let you reject him" lmao) Also if you go through with the rejection and the relationship status goes from Crush to Friends, the dialogue box about going on night dates with Hikaru + Haato's reaction to the floating text still appears.
(4) Wrong background for this one. The first time I tattled to Anna about her cheating boyfriend, it was on Shuu's route in version 5. In that playthrough, the background was the shopping mall instead of the mansion. 
(5) Also, unless the cutie VA school receptionist started sidelining as a cinema receptionist, the name on this is wrong (it's kinda funny tho): 
Hope this helps!
