You like him, and he knows that. But he kept silent and didn't take your feelings seriously. He didn't need any romantic relationship for now.

One day, you saw him sleeping on the couch again and again during work time. This time, he covered his book on his face, preventing the light from passing him

You tried to wake him up, as he flatters his eyes and annoyed.

"What is it, this time? Let me have my noon nap." His tone is stoic, but he tries not to be cold towards you, but it slips away.
