That's a very detailed feedback, thanks for your input.
The problem with VNs is that I can't keep adding more alternative routes to accommodate all possible players choices, otherwise, in a couple updates, we have 30 different routes and each one lasts for only 10mins. So there needs to be a common place where the plot comes to, and being at least friends with Emma is that common ground. Although I do understand your point of view, and perhaps didn't give it the deserved weight when considering the options the player could have to deal with the situation.
Of course you will be able to ignore all lewd content with her from now on, but it won't be possible to avoid being friends and caring about her in at least a friendly manner, even if you aren't in a "proper relationship". Please take that into consideration when thinking about playing future updates, in case that is a deal break for you.
The same is a bit true as well for some in game events, like the weed scene. I knew some people wouldn't be into that and would choose not to smoke if allowed, but I really wanted the high scene to not be avoidable (I didn't know about second-hand high, maybe that could have been a good alternative). To avoid making things harder and more complex for myself, sometimes compromises need to be made about what options to give to the player, especially when you're developing a game on your own on your free time.
