It was actually a long time a go someone (I don't remember how many) asked about why she did not included a gay relationship, and that's what she said. She did consider making it a DLC, but that is a very far future, and honestly, she didn't seem that convinced either. And honestly, I agree with you, she should only making something she is comfortable and capable.By reading comments, it seems her patrons are mostly straight men and bisexual women, so no male gay relationship will happen. It's respectable because some developers are aware of comments like straight women developers are fetishizing/sexualizing gay men hence they make yaoi games for fujoshis on DMM steam page)so Eva is probably avoiding that. She won't even include trans people from GGGB anymore due to negative comments.
