I just finished it and I can at least say that the secret ending gives ample room for it. They're certainly not gonna date those jerk offs any more lol
I shipped the protagonists since the trailer came out XD
Well the entire game is one big joke on the fact that in the timeline they date Riki and Kunio in like... one game. The other games were all the "antagonists" dating those two. So basically it's all one big delusion right from the start, which long time fans would have known since the trailer.
What I'm saying is, you weren't wrong lol
