I strongly disagree with people complaining about the epilogue. When Chapter 11 dropped, I liked it in general but criticized the lack of progression on important plot points, such as the complete lack of Cindy's reaction to becoming a model for Wildcats or more comment about that from Ivy.
In the epilogue we got both these things in abundance. The things I liked the most about this update were the backalley gossip talk with Ivy and Lena's conversation with Cindy. Both were important for story progression. Also I really liked the drama about Mike. I don't agree with people who say Lena's character was changed. While it's true that she shouldn't expect any loyalty from a guy who fucks her despite having a girlfriend, this drama was not about that. It was about Lena's sense of superiority based on the (false) conviction that she has power as a woman and can make a guy betray his girlfriend for her. The revelation that Mike sleeps around not only with her was a serious blow to her self esteem. And while it's true that calling out Mike on this was very silly (and hypocritical) in her situation, it was a natural reaction. People don't always act rationally, especially when swayed by emotions.
Cindy also behaved accordingly to her established character. People who complain that she was reduced to a dumb blond should read the whole VN once again. From the very beginning Cindy was extremely petty, selfish and greedy for glamour of being a model. She clearly disliked Lena and showed it every time. Lena too never liked Cindy and even if she got some points with her, she was always on guard around her. So the conversation between them and Cindy's stupid antics are VERY MUCH in line with her character.
So, overall, while in terms of sex scenes the update caters mostly to corruption enthusiasts (as is often the case with Lena's part of the story) it's by no means a 'story reduced to fetishism' or anything like that. In fact, this epilogue gave us lots of plot progression and generally good storytelling.
