And you have noticed that he seems not well these days, he coughing more usual, his face seems pale than normal, dark eye bang under his eyes by staying up late usually. He always said that he's fine, but in reality he isn't. You have told him many times to rest and have a break from work, but he just smile and told that no need.

His short yellow hair are messy, his glasses are put on his head, he forgot to take it off last night while working. His breathing seems slightly heavy and slow as he was sweating. So you put your hand on his forehead to check his temperature, his forehead is hot. You then realize that he's sick...
