Wen Han hadn't slept. Regardless of whether he was injured or in the military, his biological clock had formed over 15 years ago, and it seemed that he didn't need much sleep. Although his leg injury kept him from walking around, he could still move his upper body freely. He had somehow found a dumbbell and was exercising his arms.
Hearing the door open, he looked up, but was surprised to see Su Mu. He briefly showed a look of astonishment, then broke into a radiant smile,
"Awake?"
Su Mu walked over and lifted his blanket to check on his injured leg,
"You should be resting if you're hurt. Why can't you sit still?"
Wen Han smiled and casually placed the dumbbell on the bedside table next to him, "I'm used to it. If you ask me to sit idle, I really wouldn't know what to do."
"Is the injury severe?"
"No worries. Getting injured while in the military is common. Don't worry about me."
