WHAT?! Cooper will NOT be dateable?! but why? For the bit of story he seems to have a weird cute crush on Luke! You could take advantage of the whole situation to make a super cute route :(
Well, at least not in the Skies Ablaze, because he's kinda disabled for the day and I have other plans for him... but once we're done with Skies Ablaze and if people want a continuation, who knows!
