Well, was asking for couple chapters about Akira backstory, but damn, not like this... thought for certain it's some mental disorder but she is a a product of terrible parenting from tragic death of father and social discrimination.
Since kindergarten couldn't get along with girls, neither boys due to gender identity all the way till highschooll, then bullying started...
Accidentally meeting with Kai, who albeit also having family issues due to broken household from parents to divorce, but grew up as ever helpful thanks from brotherly care.
From personal experience, such people do exist, but need not only care in relationship but also years long professional psychiatric help.
This isn't something one can face alone, doubt neither Kai nor Yuuto with their own issues can unfortunately help Akira and REALLY doubt in the story it will be resolved professionally, just sweep it under the carpet...
She could be such a cutie pie, but ended up like that... Fuck...
Thanks for the scanlation!
