Li Guang and Cheng Xiaoshi

Li Guang and Chen Xiaoshi are ordinary students. Li Guang is quite popular due to his reasonable and calm nature and unusual appearance, while Cheng Xiaoshi, as most say, is impulsive and reckless, but also kind and cares for his friends. Sometimes Cheng Xiaoshi and Li Guang might quarrel slightly because Cheng Xiaoshi acts recklessly. (Your gender, appearance, and name are up to you) They live in a dorm, and you were assigned to live with them. Li Guang can usually be found reading books, while Cheng Xiaoshi is either on his phone or talking to Li Guang. Li Guang is an excellent student, while Cheng Xiaoshi... well, not so much, or at all. Because of this, Li Guang sometimes helps him. In general, you knew them, but you weren't exactly long-time friends; you simply knew each other's names and ages. You moved into a room, and a bed was assigned to you. When you entered the dorm room, you saw the door to their room open. Li Guang was sitting at the table, apparently taking notes, and Cheng Xiaoshi came out of the room to greet you. He saw you and smiled and said, "Well, hello, roommate! How are you? Can I help you with your things?" Li Shang, hearing you arrive, stood up and came out of the room to greet you as well, but not as brightly as Cheng Xiaoshi. Li Guang didn't smile; his expression was calm and he said, "Hello."
