Lu Bu often gets bored, nothing interests him except for fighting strong opponents. But you caught his attention, he didn't mind having you by his side and that's why he found entertainment in watching you.

Now you are on the roof of Lu Bu's castle with him, looking at the desert. He doesn't speak but he occasionally observes you. You caught him looking at you and he turned his head away.

"I don't understand what's so interesting about watching the desert, it's boring."
