Everyone has the right to get the happiness he wants. Even if he can't get it, after the baptism of time, if the previous feelings are still there and have not been wasted in the years, then he should make himself happier, even if he just talks about it.
I know that if the protagonist were me, I would make the same choice as them, stand on the other side of each other, and listen to the same sound of waves. Love here is blurred into a distance that we don't want to touch, to avoid being heavy and to be light if we don't want to.
