I the way my brain works I recognize patterns pretty easily and as a writer and prolific reader I tend to pick up on the commonly used tropes and thematic storytelling.
Thematically we are headed for conflict due to Makio's past interfering in his present. A resolution will appear which brings things into alignment but the conflict has to happen first and for that he must suffer the consequences of ill choices. Like not trusting Wachi or being honest about his feelings.
In Hannibal terms: He's in for a reckoning.

I believe Makio when he says he didn't do it.
I also think that rescuer is shady af. I am almost convinced he's the one who attacked Wachi.
I wonder if Makio knows more than he's letting on but he's truthful in that he didn't do it. I'm also curious about what Makio meant when he said soon Wachi will know him better. It sounds like he's tying up loose ends on the criminal side of things.
He also sounds genuinely jealousy.
