Well, at least Miya finally drew up some courage and put herself at risk. She still defaults to self-hatred instead of actually taking the other person's feelings into consideration, but I can see light at the end of her tunnel.
To be honest, though, it's Itone's development I'm most looking forward to. Yeah what she did in this chapter was pretty manipulative, but it was Yura's scheming, Miya's lying, and most of all Harutaka's spinelessness that led her to this point. Things are only going to get worse for her before they get better since she definitely knows deep down Harutaka doesn't really like her and it looks like her friends are distancing from her after she excluded Miya, but I'm very happy that she doesn't seem to be the sort of standard shoujo manga "evil love rival" that Nakagawa has written before and I'm excited to see where her character goes.
Yura otoh is a fucking psycho and while I'm sure he's getting a sad backstory I really hope he ends up in therapy and not like, with Itone as a side couple or something like that.
