Edit: Currently trying to figure out if the Tsubasa chain is triggerable on the red path.
I see many have reported bugginess on this, and yes on my red path save the last Tsubasa event couldn't be triggered it either (had manually missed all "supposed to miss" event from v0.50 but still nothing worked yet).
From a story standpoint, however, there should be more missed events but it didn't happen because Kaori's event order is so thoroughly fucked.
On the green path, the correct order is Fuck Chika at the new apartment ->
Chinami learns about Tsukasa's arranged marriage -> Akira calls Tsubasa then learns about Yuki's current status -> Akira tells Kaori her lemon assistance stand isn't necessary -> They all go to karaoke to celebrate but Akira and Nao also go elsewhere. On the red path, everything underlined should be missed, but somehow not the last two. Selly can and should've made path variations for it, but consequently it would butcher the order-fucked Kaori event A LOT, as red path Akira should have no knowledge regarding Yuki's current status, and thus should have no rationale to have Kaori stop what she is doing, and have no reason to call Yumi, and Yumi would not have sweet moments with Kaori, and they wouldn't be celebratory and go to karaoke. MUCH needs to be changed and MUCH will but should be missed from a logical standpoint. It makes refusing Tsukasa a much bigger deal and makes red path boring, but I personally think Selly needs to stick rigidly to whatever path variations he himself designs.
