Hey there! Thank you very much and I'm glad to hear that you enjoyed it that much! I try to be not overly cliche or comedic, but sometimes it fits the scene, so I'll add some parts here and there.
If you can't join the Discord because the invite links says "Invalid", then it's because you have to verify your age on Discord. There are some post here on itch which ask the same and we figured that out at least! Sadly, Discord requires age verification in more and more countries nowadays. Though, I wouldn't trust any company with my personal data in this regard, so be careful.
I haven't really planned a fixed amount of chapters. I see myself working on Chapter 12, 13, 14... because there is just a lot to tell and experience as well as building the relationship with the girls to a point where it makes sense to have a harem route and where it feels like they all belong to the world and the group. Overall it also depends on how people receive the next updates and if I can invest more time into the development in the long run.
