Sometimes love is an eternal memory, sometimes it is a heavy past. "Tears of the North Star" was originally a sad love song, but it allows both lovers to hear each other's voices. Its existence illustrates the true meaning of love. Love is not about loving each other forever, but having the perseverance to face the setbacks of love. Even if we are separated, our hearts can be together. No matter how big the obstacles are, it is enough for our hearts to be together.
