While I agree that the Keisuke-Miyabi focused chapters would've done better in Vol. 2 of the main series, I honestly am just so pissed off with Sasabe's attitude that I wouldn't mind not seeing him for a while. Or just have the rest of this series showing Utou finding happiness with someone else who deserves his kindness.
Unfortunately if u wish for Keisuke and Miyabi to appear more, then Utou and Sumito will never have any development nor can they achieve their happiness. Ur being cruel and unfair to the main characters. I could see Utou glaring at Keisuke and Miyabi for snatching his story away from him.
And if u wish to not see Sumito then the story will rewind all over again, making it as if Sumito is being raped over and over as it waits for a continuation because the author is too focused on supporting characters.
And I personally thinks that Sumito's attitude will change by time. It depends on how the author wishes to write him as what characteristics.
So... let me get this right... his name is... Nakajima... Yuuto... like from Hey! Say! JUMP lmfao.
IKR!!! I was like the author must be their fans!!!
And the brother kinda look like Nakajima Yuto somehow...
Lol
