here's another one in tenma's point of view. it's kind of obvious who it's about.
Watashimo Gomenasai
"I was, and am alone,
Or at least that's what I was always told,
And I'm sorry,
That I never opened my eyes,
And used my sight for myself,
Could you forgive me,
For not trying to see what was real?
Or do you too, wish the sight of me,
bleeding on the cold floor?
About to take my last breath?
Do you hate me now,
For never looking at the world like you?
Who could always find a reason to smile,
And who was always there to protect me?
You never wanted me hurt,
But, one thing you didn't know,
Was that I was always hurting,
And there was nothing that could be done,
Or so I thought,
You tried to change my perspective,
But I instead tried to push you away,
And for that,
I have no reason for you to forgive me,
And yet you've always done it anyway,
