I'm ready for anything.
On one hand, Rika did like girls, but on the other, he also once implied that he needed to like girls as he was a guy. He's just starting to discover himself so bisexuality or not, it'd be interesting to see. Either a cis girl accepting and loving him for who he is, or Satsuki realising he's still attracted to this new, fully masculine Rika.
Also, bisexuality and gayness are still touchy subjects in the trans men community, especially bottoming as non-op, because many like it but still feel it somehow makes them lesser of a man. We should just do whatever we want but social stigma + dysphoria are super strong.
This is one of the few stories whose art style I wasn't much into but the story carried itself perfectly, and I'm happy I found it (I do loved how Rika looked after his transition though).

Mate, I'm so sorry to say this but you should leave the translation to someone else. I see there's not uploader, which means it's mangago automatically importing this from some other site, but if the translator happens to see this: your English needs a lot of improvement.
And that's not a bad thing, everyone gets better eventually.
My ADHD usually adds even more confusion to bad translations, lol.
I bite my boyfriend's cheeks too and that's 100% out of affection. Just be bisexual man, you don't just like that ass but you like his dick making a Niagara falls out of him, stop pretending you don't want to see it.
