In my humble opinion, chapter 6 was the hottest update yet. Really took it out on Ari while Vi was being a slut somewhere else, I love the influence she has on her and I think Ari is starting to mark her new territory with the MC. She's driving Vi to other men which spurs MC on and Ari would be there to take all his frustrations out on. That'd be the perfect dynamic for Ari, she'll want MC for herself but she knows in order to keep it fun for her she'll need to manipulate Vi and MC's love for each other to act out around them instead of with each other so Ari can try and have MC all for herself. Since it doesn't work without Vi it's crucial to keep MC and Vi officially together, so Ari has Sai for cover and Sai is warming up to the idea of Ari fucking around with MC.
Really love this VN, normally I'm no fan of Kinetic Novels but this one is fun to watch because the choices the MC makes usually coincide with my own choices. Pretty sure I promised I'd support this project on Patreon when the next update drops, I will hold to this promise.
