He smoked when he was troubled.
Seeing Xiang Xiaoyuan staring at him, Lu Wanggui explained, "I've been troubled recently."
Xiang Xiaoyuan was puzzled. How big of a problem was it that even Lu Wanggui felt troubled? But it should have something to do with work. Xiang Xiaoyuan wanted to help, but she was just a rookie compared to him. If even Lu Wanggui couldn't solve the problem, she couldn't be of much help.
Fortunately, Lu Wanggui added, "It's not a big problem."
Xiang Xiaoyuan nodded. "That's good."
She smelled the faint smell of tobacco coming from Lu Wanggui's body. She couldn't help but wonder if this was the difference between fictional and the real world? In the real world, she hated the smell of cigarettes. In addition to smelling bad, secondhand smoke was bad for the body.
