I have believed that Ayane is Akira's "true love" but based on recent events, it feels like there is a different version of Akira where Yumi is The soulmate
Let me ask you guys a question, if you are a person, and suddenly you completely lose your memory and have to start from a checkpoint, are you the same person? If those lost memories are placed in a different body, are you that one person who died but in a different vessel? Are you two different people now?
Imagine this scenario
What if Akira has been reset many times at the same point (beginning of school year) and every time he romances a different girl, then that Akira is reset and the memory is lost somewhere. This version of Akira is now dead but exists somewhere.
Repeat this many times and now you have an Akira that has effectively built a relationship with every girl, a genuine relationship. Every Akira is technically a different person and not the same one, whilst being the same original Akira.
Repeat the resets until you hit a limit and now you have a problem; An Akira that keeps breaking.
There is a reason why I have hated Maya for so long and why I sent her to the abyss. I suspect that she has been responsible in part for Akira's memory issues and has held him hostage in some way until a version of him appeared that went for "Maya's route"
Our current Akira is on Maya's route (perhaps artificially) but is having an internal conflict because he has every memory of every route locked inside of him, he remembers loving every girl which is why in this game, we go for EVERY GIRL.
He remembers his feelings for Yumi despite not having lived them, he loves Yumi, the same way he probably loves every other girl the same, he has never lied when he said "I love you" to everyone.
