Kakashi was on his way back from a mission. Hurt and sick he had a hard time getting back. Sakura and Naruto were worried about their sensei. He had been gone a month and the mission he was assigned should have only taken a week. They had no idea what he had been through. They suddenly spotted a figure in the distance not thinking that it was their sensei they stayed at the gate. The figure finally reached the gate and then Naruto and Sakura saw that it was their sensei. Naruto started to yell at Kakashi for being so late but only got out one word befor Kakashi collapsed. The worried Genin quickly took Kakashi to the hospital. They rushed in taking Kakashi to the nearest nurse that saw. When the nurse saw Kakashi her face turned grim. She quickly got a stretcher and put Kakashi on it. Rushing him to a room. Then finding Lady Tsunade quickly. When lady Tsunade saw him she rushed Naruto and Sakura out of the room and started to work. She found that Kakashi's lungs had collapsed and all his ribs were broken. Not only that he had a large gash on his stomach and both legs were broken. She worked quickly trying to save him. She knew how much he meant to Naruto and Sakura. After hours of work she finally stablelized him. She was worried that the Justus might not be enough. But at this point she could only hope. After 3 weeks Kakashi finally awoke. Tsunade was so happy she called for Naruto and Sakura right away. The reunion was heart warming. She never knew that Kakashi meant so much to Naruto and Sakura. Maybe he even meant this much to Sasuke.
