these are so funny and i'm glad rin can't pitch a fit about "IS BRINGING YOU BACK HOME NOT ROMANTIC ENOUGH????" (no, idiot). food can be a love language though and aak deserves better than convenience store kibble
lbr aak is also good at compartmentalizing people caring about him as many different things so pinning down something as wholly romantic becomes difficult
like the most romance-coded things he's said to rin and genya were "i don't want to regret not trying [with you]" and "i'll patch you up if you get injured"
