Nah, my guess is that we'll get a flashback of the girls telling the opposite legend, that the ones that kiss in front of the castle soon breakup, so we will get an arc of Junichi trying to get to the castle, Yame taking him away from the castle, him believing that it is a sign Yame doesn't love him anymore until they talk things out and have a kiss somewhere neutral and promise to be together without any legend in the way.
That said I still like Yui more than the other girls here so if Yame goes away, not a huge loss for me.
