I wish he’d ended up with the blond guy

Aren't we all?
as I am very NOT happy with the ending I imagine after miki got back to his childhood town, he settled there and found his own friends-and-found-family. He had to go back to his family town and reunited with the twin brother and that shitty family (also the disgusting pedo since the twin bro is such a snitch) when their grandma is dying, but miki reunited with shimazaki (the blondie) and they're git together!! And that's the happy ending we (and miki) deserve!
would've been good if it stopped at ch 4
