Well the new chapter is... Is... I will be honest I didn't like it very much I mean, the Felicia's friend (Maribel) is sexy, is very good maked (The art, etc) but is a friend of the FMC, the game is a "NTS to NTR" game where the girlfriend start a cuckold relationship with the MC and after a time she start to make things at the MC's back and I know Maribel was necessary for the chapter 5 because Felicia had blocked the MC and if the plot don't do something the story was finished there but after that Maribel is unnecessary, it's more a character for a Spin off where she have a relationship than a character with chapters in Felicia's Story.
It's more, I will give you a good example of what I mean, in this site there is another game like "Damn that's Felicia" called "NTR Phone" it is not exactly "the same" but is same style, a game with a phone format where the user interact with the characters of the story through a chat system, in that game you can find various FMC but every one have her own story independient of each other, something like that it's that I whant to see with Maribel from now on I mean, give her own story separated from Felicia's story and no, I no mean both story must be 100% separated I mean, Felicia and Maribel can interact if it's necessary for the story but, don't give Maribel a entire chapter for her and nothing about Felicia, it's better give Maribel her own story because remember we play the game for Felicia and her story with the MC, if Marybel would have been from the begining of the story and the MC had at least a signal that make the user think "He can cheat on Felicia like Felicia cheat on him" maybe Maribel's presence in the story don't feel that out of place and "unnecessary" passed the chapter 5 where like I said before she is practically obligatory to interve.
