Hi there! First off, I just wanted to say thank you so much for making this patch. This is the kind of thing that I've always longed for in HM/SoS games and I cannot express how appreciative I am of your work. I've been playing with it a little bit, going for Ludus with the male build, and having just gotten his reverse confession I noticed some dialogue that could be addressed should you continue working on this.
In the reverse confession, Ludus still refers to you as a 'little sister' when talking about when you first met. He also uses the term 'girlfriend' as opposed to boyfriend. After the confession, talking to Siluka and Iluka results in them each congratulating you as if you started dating the other sister-- I assume because of the way it's trying to handle dating Ludus as a male. Shalck and Alma hilariously refer to Ludus as 'Big Sis Ludus', I assume again because of the way the game is handling the event (there are only Big Sis Iluka and Siluka in Lulukoko, and thus the programmers just added <Character Name> code into the dialogue string). Tototara correctly gives you the dialogue you would see if you were playing as a female and started dating Ludus.
Again, thank you, thank you, THANK YOU for the no doubt difficult and tedious work you've done for us players. It got me to pick the game up again. <3
