"I realized I want to be with Haruka-san forever"
Hmmmm how long have these two been together? A week or two tops? Maybe not even that? (this is chapter 4 and they got together at the end of chapter 2) Nobody else thought that was way too much, way too soon? Just me? Okay. Not a major complaint btw, I just thought it was a bit weird.
I kinda love Haruka's friend though, good thing that she's looking out for her pal.
