The point of the bad ending was boundaries , even tho we are going this kinda relationship ( doesn't matter she liked it or not ) , she does it out of love not pure lust , we're going slowly and Ayumi is not comfortable doing that NOW
However , I agree this shouldn't be bad ending but makes me wonder , how are we gonna fix it like , end the night because her emotions conflicted , wait few days than she come to us saying she wanna continue ? but that would be diffrent route cut off some writing ( this is what I would tought / do )
At discord Tori said she changed the bad ending
What has changed is that now it isn't an automatic Bad End anymore. After the main part of the scene plays out, there's an additional choice. This choice can lead to the original Bad End... ... or it can lead to the continuation of the game. To avoid the Bad End, MC needs to apologize. There is a hint at potential long term consequences, but nothing implemented so far
