in all seriousness i think it's because compared to all the other LIs, robin is the only one who can offer a genuine, somewhat healthy relationship to pc, & has a history with pc to begin with,, & therefore is the only person who is a "real threat" to being the #1 in pc's life
that bottom left guy is anything but a cinnamon roll but i can't think of anyone else who fits (not an excuse to put him in there srs srs)
