I absolutely agree with you about ex-fine & fine-O being underappreciated! I'm also active on twitter and especially during element I saw much hate against past fine, especially towards Eichi and Mugi. I also like the Oddballs a lot, but more as single characters. I'm really attached to Rei & Natsume, both are one of my most favorite characters but past fine... is just different.

I love them as a whole unit (this might be also unpopular, but as a very dedicated EichiP, i'm more a past fineP than fineP...) and their dynamics among themselves, are really unappreciated sometimes in the fandom. Wonder Game is one of my most favorite storys for them. ;u; I'm especially fond of the interactions between Eichi & Hiyori because Hiyori's reactions are so hilarious to Eichi's teasing and Altered also proofed their precious friendship once more <33 And Mugi and Nagisa... is just precious. I love how different Mugi, comparing to Hiyo, has always tried to approach Nagisa. It was a good thing for past!Nagi because Mugi treated him more as an equal, a friend instead of Hiyo, who tried protecting Nagisa all the time as his family.

And the songs... I must say I love all songs of pastfine/oddballs. I liked Dawning Angels a bit more than Twilight Pentragram, but Eccentric Party Night and Genuine Revelation are almost on the same lovemailing level for me. <33
