What is youth? There are emotions, tears, and sweat. I love going home with you most, gossiping during class, and every moment with you. But when we walk out of campus, we become more and more distant. When we return to campus, those young faces are just like us back then. Well, I want to turn back time, even if I give us a year to get along, I don't want to leave any regrets. I don't know what will happen to us in the future, and I don't know where we are in the world now. But I hope that we can meet at the next corner and still be able to smile and say to each other, long time no see, I miss you.
