So that was why Momo said she "maybe never will" fall in love. I have a feeling (it's pretty obvious tho) that the little sister (Hajime?) has a crush on her but as we know in this chapter, sadly would not be reciprociated.
It's quite a suprised open the comment section and saw quite an argument going on here lol. Shiho to me was a flawed, self-centered, quite unlikable yet somewhat very humane. In short, she's an interesting character, I would like to see how her story would lead too, and her other band members' story as well.
