So Alert?

Harper had slept alone in his room since he was three years old. He didn't let anyone in and didn't like to go out. In the blink of an eye, he was already eight years old, and this was the first time his father had accompanied him at night… He slept beside him and guarded him…

Harper couldn't describe what he was feeling. All he felt was that he was no longer sleepy. Suddenly, he heard a rustling outside the door. He didn't know what it was, but he frowned. He thought about it and got up to go out and take a look. As soon as he got up, Dylan was woken up and asked, "What's wrong? Want to go to the toilet?" Before Harper could answer, he wiped his face and stood up. "Let's go."

Dylan wasn't the talkative type. When he saw Harper looking at him as if he wanted to say something, he waited quietly. Father and son stared at each other.

Harper pointed out the door. "Dad, didn't you hear it?"
