Just finished this, but I have two questions
(1) Is the point where Haru says Kyousuke is Maou after Tsubaki's brother's kidnapping just an inconsistency? From what we were given, I know Kyousuke's headaches and vanishing at certain points were meant to sort of misdirect the reader and certainly very suspicious at the time but Maou(Kyohei) showed up in front of Haru during the bombing that killed her mother. Since she and Kyousuke were more or less the same age I assume give or take a few years max, that makes it pretty much impossible Kyousuke is Maou since Maou had to have at leas been a young adult at the time.
(2) For Tsubaki, Kanon, and Mizuha routes is Kyousuke considered to be Maou after all? Not 100% sure about this one but for Kanon's route I recall Maou does tell the Sannou guy something about finding love.
