Thank you for the feedback! I think you have a good question, and it deserves an answer.
The VN isn't planned to have a harem... yet. With where the story is currently, it's just not feasible. The (evil) characters that have been introduced so far (demons, futa/trans, captors, prisoners, etc) all play specific roles for the MC, with those roles having a conclusion after a couple chapters/updates.
This VN is planned as more of a "2-part" story arc. It will take a while to tell this story and get through this first part. The 2nd part (planned to start in Ch 06) will be more laid-back, lighter fare, and have an opportunity to have a harem-like experience.
There isn't really a way to "avoid" most of these early relationships, since they are important to the story. But these scenes can be considered "skippable" in that you just don't have to see it. I will be including as much content as I can when it comes to the LIs back in MC's home, but the story limits how these interactions take place.
Sorry I can't be more specific without spoiling the story, but it's the best I can do. I try to update the change log with specific kinks/scenarios, and preview images with each new release. If you see something you like, I encourage you to take a look.
Thank you again,
