Not sure how exactly I feel about this one. On the one hand, it's nice to see Cio being so direct, skips a lot of the screwing around that normally goes on. On the other hand, while Cio has been pretty clearly interested this whole time, Allison hasn't really showed a strong reciprocation of those feelings. There have been a few little hints but nothing that screams: "I like you!" from her corner<snip>
Like... isn't that okay, though? It's really damn rare to see in fiction but it can be nice to encounter a relationship where one or both sides just kinda' ease into things. A more chill build up... relative to the gut stabbing and whatnot, anyway. No need for strong reciprocation or screaming
(well, on screen anyway *obligatory wink wink nudge nudge*), just folks getting along more intimately than usual. Smooth fluff, as opposed to the spiky and on fire sort.
Though actually, now that I think on it a second, lily-flavored (maybe homosexual in general, I don't browse enough male on male to have too strong a handle on common themes with them) romance plots having one participant being notably more aggressive/interested/whatever are fairly common, so I'unno. There's an argument it's a fairly normal romance scenario, I guess.
Conceptually it's common with romance in general but that particular setup also has a nasty habit of getting real sketchy real fast, and at least when they're not playing fan-servicey molestation angle yuri/femslash/whatever tends to be fairly on the up and up when they're running with that sort of character interaction.
