Is this Pareidolia talking about Saki? Did Saki enter Akira's bedroom to cry about losing Yuu? And if she did, why did she do it to Akira instead of Nozomu (?) - maybe there's a simple answer and Nozomu simply looked like her instead of his father.
I ask this because at one point Pareidolia, or maybe Sekai (?) - can't remember, also talked about how if he continued on the path he was on he'd end up like his father.
Whatever that means I have no idea. But it would be an interesting twist if Saki didn't abuse Akira at all (not in how we expected her to), but more that she "didn't like him" because he reminded her too much of Yuu who apparently suffered a terrible fate. This would also fit with the kind of neglect Ayane probably suffers (with her father being reminded of his wife by looking at her). Maybe that's why Akira grew closer to her and yet never had a romantic inclination towards her idk.
Edit: Okay, apparently Yuu had severe psychosis...
yeah, I can see the parallel now.
Edit2: I can totally see how a religious Saki that lost her husband to mental illness, would make Akira keep praying to wish the "demons" away (his mental illness), and generally dislike him because he'd remind her too much of Yuu. So he was probably praying since childhood to stop hearing voices and the like so that he could get his mom back, but "god" never answered. Sekai could have been drawn by this person that also felt that it was impossible to breathe and found her bizarre definition of love with him, instead of the "normal" Nozomu. Then when Sekai died, his psychosis got even worse until finally the "voices/god" started answering back. And here we are.
