Yitian was coming late from the library, so he missed all the trains home, leaving him the only choice of walking back. He had last money and he couldn't take a cab, because he wouldn't have left any for food the next day. His mom wasn't home for three days straight so he needed to make some food and wait. But Yitian had to say he was not so afraid now. She wasn't home, he hadn't made any problems in university and soon he will leave for a field trip, leaving her again. He had even arranged some tutoring, so he would have pocket money and buy a phone. Then he would find Chao at his faculty and be friends. Without a phone, it would be useless to find him because he would have no way of how to keep in touch. So, soon he would go to the Faculty of Computer science and ask around.
