Same thing happened to me.I believe for the other characters (hifumi/shogo girl too!) you need to actually be in a romantic relationship with them to trigger it (I assume rank 10 for the rest of them). I think Makoto is kind of the "default choice" in that situation for whatever reason so you don't only have to hang with Ryuji. There's a similar situation later where if you don't have a romance there's a "default girl" and Ryuji to choose from, but I had romanced Kawakami by that point.
I see! Thanks for answering!
Lucky for me, I was on the fence about pursuing Makoto, now I'm all in cause of that scene. Best girl.
