The official pairing feels really forced to me. Yori x Aki seems more natural.
For me it's the other way around. Aki's feelings for Yori feel a bit forced for me while Yori x Himari feels really natural.
I don't get comments like these.
What's forced about -any- of those relationships? They are all dynamics that, y'know, happen. All the time. People falling for cool upperclassmen that are in a band? Ohhh, yeah. People falling for their best friend, or becoming friends with someone hoping it'll become more? Definitely. People falling for cute underclassmen that come up and confess to them (she thought) after school? I mean, yeah. Those are all pretty common, natural things. Where's the "forcing"?
I get liking one pairing better, thinking one pairing has better chemistry or whatever, but "forced" just seems like a sloppy way of saying "I don't like it as much."
(and if you don't like Yori x Himari, I'm not sure why you stuck around after the first chapter, because it's not like the series has been subtle about them.)
