When we think we have the ability to love someone and promise to wait for several years or even a lifetime without any guilt, we are still troubled by such inexplicable love. It cannot be said to be sad, because there are too many sweet throbs and joys. This kind of love can only be felt when you lower your head and hear your heartbeat. I don't care about everything about that person, yes, everything about him, even if he is poor, even if he is bad, even if he never knows that there is such a person who likes him very religiously, so what, I love him, not the sunshine behind him or the shadow of his head. This kind of love can only happen once in a lifetime. It lives in our footprints. Such a clean but incomplete love once filled these deep or shallow footprints with sad tears after a certain drunkenness. We are getting farther and farther away from these footprints. We can no longer cross those tearful footprints to go back to the past and return to that person. Because I am afraid of suffering for love, I can only walk in front of memories.
