It's not old yet, and we're all gone. I think it's particularly realistic, because there are many promises in this matter. The feelings of youth are beautiful, because he is particularly pure, but then everyone separated. For commitment, for youth, we all separated. The purpose of this matter is to make a lot of promises. I think everyone needs to abide by it, but in youth, we have to separate. It's not because time changed us at first, but later we didn't think so. I think it's realistic that young feelings can't persist, because there are too few feelings that can persist in this world.
