This update provides better renders and beefs up some of the m/m content to provide options for fans who felt a little frustrated because they felt somewhat shoehorned into certain scenes during the first part of Act 1.Does it have new content on f/m route or just better renders on existing content and new m/m content?
Depending on your own head canon the original makes complete sense as MC is going through a bit of a sexual awakening.
However, there were some fans who just felt the m/m should be more front-loaded right out of the gate in order for his sexual awakening to be exclusively m/m. Which to be fair, is not an unreasonable argument, even if it created a ton of extra work. But, the developer is a benevolent and awesome developer as stated earlier and decided to give the people what they were asking for.
I believe the next update also adds more m/m scenes in addition to updating more of the renders. I can't recall if there would be more f/m content added in that one...but I want to say that there was something planned. Though that could be incorrect.
