thank you so much! Ah, and I want to ask one more thing. It's about the relationship with the girls. How could we know that we are getting closer to each other and are things like eat together or study together make us closer?
To improve your relationship with the girls, the most important thing is to do their personal quests. As you do them, you will unlock more interactions with them, both sexual and everyday, such as eating and showering with them. At least once it's implemented, which will be soon.
Katsune, Fuyu, Yuri, and Kokoro's first personal quest is available at the end of Chapter 2 of the game, which is after completing the clubs story. This upcoming update 0.3 includes chapter 3 and when you complete it, you can do the first personal quest from the other main girls.
Your main story decisions serve to make them happier or angry, depending on which ones you make.
Currently, eating with them is useless. I have yet to add more utilities for this.
Wow! I'm afraid I have no idea why this is happening or how to fix it. There's no way this could be due to a mistake on my part, I've never put those characters there in the first place, so there should be no way for them to show up. The game just seems to have gone crazy.
Does that bug always appear? Does it prevent you from continuing to play normally? If you leave and enter the map, is it fixed?
