Holy SHIT Ryota is starting to piss me the fuck off, bro. I can understand his sheer TERROR about being intimate and romantic with Akira to an extent but GOOD LORD. Bro is acting like he's ALLERGIC to her affection. What happened to that whole "well what if what i said wasn't just an act?" from the last arc??? Maybe it's the Akira fanboy inside me but seeing him act like such a (for lack of a better word) FUCKING PUSSY just makes me want to reach through the screen and smack him upside the head.
They are "siblings" in the most LOOSE sense of the word, THEY'RE NOT EVEN LEGALLY step-siblings since Akira is still keeping her dad's family name. Ryota as of now has the whole "don't know what you have until it's gone" character arc written all over him. You KNOW if Akira even HINTED that she was romantically interested in another man and tired of his "bUt wE'Re sIbLIngS!" bs, Ryota would be having a fucking crisis.
The Male MC's from ACTUAL incest romance manga's have more backbone than Fucking Ryota. At least they're willing to stand up for their romance and love, and they have to deal with the consequences of ACTUAL INCEST.
