Hmmm there's certainly something wrong with this, is undeniable... Remember when we were reading Shinozaki san or Swap x Swap? they keep using the same trick over and over and over again, but you know? only after 25 or 30 chapters I felt "uhhhhh... this is getting boring" because it was starting to feel silly.
The fact that this manga managed to feel silly for many of us with only 2 chapters using the same trick is proof enough that it wasn't handled well... Someone said "It's normal for gag mangas to do stuff like this!" yeah... But done well.
"is because Kanochi is afraid" that should be a solid reason except that Miyu totally ruined her chance to explain and hasn't made any progress trying to fix that
Here, when she confessed for real, it was her chance to say "no, not for the manga" ... but no, she didn't and now Kanochi is 100% sure that she's doing it for reference only and all that comes next are the same.
So, because Miyu is unable to comprehended something so basic, I guess we have to wait until someone snaps and leaves the team without explaining reasons and then come back together in a dramatic fashion.
