Some people have suggested that this was written after the attempts to revive Aqua, but then it makes even less sense because it basically turns LN into another bait and switch and completely devalues buying/reading it because then the extra tells you the consequences of things already “a couple of minutes” after LN just started teasing it. So it's likely that Akane actually became even more obsessed. Unless you like the idea of Aka reaching a new peak of poor planning and writing even after the finale.
After the live action and Taiki's words, it was as if Aka himself signed that the ending was crap and Aka just wasted our time trying to justify it. But yes, Aqua's act actually romanticizes suicide as a radical solution to supposedly "unresolved" situations. Moreover, the way it was written seems to motivate suicidal people to break off all social contacts and rush through it without thinking about anything, because “don’t worry, your relatives will deal with it in time.”
