After re-reading the entire route, i think that on Day 22 Aki should confront MC about dating Shoichi ONLY if you told Saya the truth on Day 21, considering that (if you lied to Saya) MC thinks about both (which are mutually exclusive at the moment) Aki and Saya threatening MC when mentioning how MC treated his ex-girlfriends.
Considering that and regarding issues in my previous post, i guess the only time things worked as intended was on Day 29/28, during the conversation between brothers on their way to school.
In case you had the fight with Shoichi (Route C), in this scene Aki talks about how Sho isn't doing well and communicates with his sister even less.
If you told Saya the truth on Day 21: Aki murmurs that its hard for him to trust MC, because MC doesn't talk about stuff with him.
If you lied to Saya on Day 21: when Aki asks if something happened between MC and Sho, he also mentiones that he knows that the two of them are dating.
I guess those two should be switched too (?).
While a lot of inconsistencies were smooth out in the Update 0.65, one issue remained and a few others were added.
Main problem: Regardless of telling truth to Saya or not, Aki confronts Shoichi and MC about dating on Day 31 (Route A) or 30 (Route B), when the boys are cleaning the kitchen, before going on a date to the park, wich creates most of the issues listed bellow. I guess either this scene should be tweaked or/and the reactions to it later.
Tell truth to Saya on Day 21 - Aki asks about a dating advice the Next day:
Day 34 (A) / 33 (B): New conversation in the morning is a bit odd, considering that Aki already confronted Sho and MC about dating during Day 31.
Day 36 (A) / Day 35 (B): Last 3 lines, same issue as the previous instance.
Day 38 (A) / Day 37 (B): Same issue as previous two instances.
But after Shoichi comes for the sleepover, everyone act nonchalant, when Aki calls Sho MC's boyfriend.
Day 35 (B): Shoichi blabs about his boyfriend, Aki pretends he didn't notice anything.
"Deny it" in conversation with Saya on Day 21 - Aki confronts MC about dating Shoichi Next Day:
Day 22: After Aki confronts MC about dating Shoichi, MC still mentiones that both Saya and Aki threatened him about dating Shoichi, when these two scenes are mutually exclusive. Was mentioned in my second post.
Day 31 (A)/ 30 (B): After cleaning the kitchen, Aki confronts MC and Sho about dating, even all three of them know that Aki knows about the couple.
Day 34 (A)/ 33 (B): After Aki told that Sho and MC should tell their families about them dating, Shoichi says that MC told that Aki knows, despite Aki confronting the couple already a few days ago.
PS: Ive noticed that lying to Saya no longer affects you getting to route A or C anymore (sometimes?), but im a bit confused what other choice does, aside from the two involving Sho's dad.
Keep up the good work.
