I would LOVE [haha] if CREA pops up again [HAHA!] on these songs
But if ''again'' refers to something that's happening one more time, I think that collabs with JUNO and/or URATA are much more likely. When she collabed for the second time with URATA, the song was called "ANother song", so I wouldn't be surprised if they sing together again [oh, I hate how every sentence about this mini sounds like a pun]
I think there'll be a winter song on this mini as well. If so, it should be the theme of a dorama or an anime, and then BAAAAM instant hit. Also she would be singing her ass out of it in all those special music programs that come out of nowhere in December... The lives for Days were all amazing, mainly that one with SEASONS acapella before it (:
