Selfishly, I hope Hotaru and Nekome don't actually become a couple, I do like the way Hotaru cherish Maki and sees her in a special way even if she hasn't realized herself, and they seemingly have good dynamic, and I do also like the angle that the two main characters are not/will not be together, giving them a friendly chemistry unusual for the genre, and ultimately, the development of their "partnership/fellowship" towards breaking Shiratori's shell.
Fingers crossed,
