Wow, if this is true (I'm still doubtful about it, it seems surreal), it really might be one of the best entries of the series. I'm so happy about it. Bisexual characters ?? Several bisexual characters ??? Several bisexual important characters ???? Am I dreaming ? I just needed that to say that I'll enjoy the hell out of this game.
If I was nitpicky, I would say that I would have loved for the characters to have bisexual relationships between each other, and not just toward Byleth. And I hope that S-support is not just for Byleth, that would be a shame. But well, that's super good news nonetheless.
