As far as I understood the original idea was to have little A going with people one at a time, final-boss style, but the author noticed people were craving romance and went with the idea of romancing one of the two characters he had already interacted with, so Kendrick should be the one and only. But considering the story I'm not convinced that that will keep little A from 'helping out' others, too, so perhaps K will be the only one getting real romance, but the others will still be helped?
To be honest considering how the first season ended I wouldn't be shocked if the second season went in an entirely different direction, but this author is so hard to predict, plot-wise (which I enjoy. Like. Came for the smut, stayed for the plot? Insane twist!), so... who knows
its like, otome games, gamers get several love interets = several ending
Love the fact in the end it won't really be harem but not one relationship either. Or maybe I didn't understand right but hope I did because I like this game like idea. (By all means I love lil a and Kendrick but I'd also like seeing lil a with a few of the other characters.)
