If the author was that keen on Daiki and Sui being end game then the least they could have done was put in some kind of redemption. Like "Oh, he feels bad that he raped and he was punched" is not redemption. Dude didn't even apologize. And, the manga never even explained why Sui had a crush on this dude even before he met him.
This manga is rushed like there are parts of the plot missing and the author forgot to put it in or my guess is that they didn't completely think out the story line
