Thank you for letting me know. The tags and the start of the game don't give any indication of this. I am fine with any kink as long as it is optional. I sub to several dozen creators who have three things in common: they are talented, make all kinks optional and I love their work. This game has been so sweet and wholesome that I would never have suspected that the creator would force the lesbian kink on us. Everyone has their own kinks and I don't judge but I do not have the lesbian kink and any Li that is bi-sexual turns me off. I always ask before I invest my time, energy, emotion and money into a game. I wish you folks well but obviously this game is not for me. Tis more the shame because I was really digging it.
Nothing wrong with having a taste or distaste for some stuff. I personally like this kind of "mixed" games and Yuri games, but that's not for everybody. Just like you I have my own distastes. For instance, I don't like Netorare games (but I am fine with Netorase and Netori stuff). I also don't like those completely lame protagonists that need hypnosis, blackmail, violence, rape, humiliation and more of that "fun" stuff to have sex with a woman (but I also don't like protagonists that crawl in a corner when someone says something unfriendly). So I get where you are coming from.
Personally I also prefer to know when something happens in a VN that goes against my tastes by giving tags or notices beforehand. The worst VN's are those that start very promising and than "out of the blue" hit you with something you could not predict because it's "telegraphed" nowhere in the VN (yes I'm looking at you "Business of Loving" with that completely unexpected Netorare on one of the main characters I was busy building a relationship with). As you can see I also drop VN's when they contain something I don't like. Sometimes even with a touch of sorry (for instance - a lot of Netorare, rape or other "fun" VN's have top notch graphical art).
So - Feel free to drop this VN if you don't like stuff in it. I think everyone does that here on a regular basis. As long as people respect other ones choices and don't judge people, there is nothing wrong with that.
