Mu Yuan is suffering from a high fever that won't go away. Jack went to find some medicine to inject into him, but it still didn't help at all. He could only use the most primitive method to cool him down. Mu Yuan, completely unaware, leaned against him, and Jack gently stroked his head, feeling relieved. Mu Yuan always kept a buzz cut, which Jack had teased him about. He asked why not grow out his hair and style it, but Mu Yuan said he was lazy. This habit arose in his youth: in five minutes the army would assemble, leaving only five minutes to brush teeth, get dressed, and head downstairs—no time to fix his appearance—and a buzz cut was the simplest and easiest to manage. Jack commented that having a hairstyle looked great, that no eighteen-year-old youth would sport a buzz cut. Mu Yuan said it didn't matter, he was handsome, and a buzz cut was the ultimate test of handsomeness; if it mattered, Jack should try a buzz cut.
When he met Mu Yuan, Mu Yuan was only sixteen years old.
