"I just remembered there was no water on this chair earlier."
Since he'd just enlisted Ding Sihan to plot against Lin Li, Bai Bufan couldn't help but suspect that Lin Li, who holds grudges even smaller than Ma Yan, might retaliate.
That's why he was so cautious when he walked in.
When he pulled the chair to sit down earlier, the movement seemed smooth, but actually Bai Bufan intentionally glanced at the seat surface to make sure there was no water before he pressed against the chair back to sit down.
The reason for pressing against the back was to prevent Lin Li from pulling a fast one and snatching the chair away at the moment he sat down.
But he still got caught.
"Could it be my sweat?"
With this thought, Bai Bufan touched his buttocks, then smelled his wet fingers, and chuckled in relief:
"Oh, it's pee. I mean, how could someone like Lin Li, who's not really a champion but just a winner, make me sweat?"
