Ordinary and unchanging daily, calm and peaceful campus, Companion and less connected students, her around, and them. It’s just awkward to connect people who are not connected. Everything starts under the blue sky, Then everything is gradually being broken. Fall into panic, fall into pain, and even die. However, it will not give up. No matter what kind of past, no matter what the present is. Even if the future is already doomed, still be able to keep the promise. Just because of the blue cockroach. She is still smiling so far.
