Fo Li now has a good feeling towards Shangguan Linlang, so naturally, he sees Xuanyuan Wuji as a stumbling block.
For a stumbling block, Fo Li has always felt there's no need to endure, you just need to... kick it aside,
So, Fo Li is of course willing to see Shangguan Linlang showing a 'cold and heartless' attitude towards Xuanyuan Wuji.
That way, Fo Li feels like he finally has a chance to replace Xuanyuan Wuji...
Thinking of this, Fo Li is so happy he could almost jump for joy, but such childish actions really don't fit his identity, so Fo Li of course wouldn't do it in front of Xuanyuan Wuji.
He's not worried about Xuanyuan Wuji being angered to the point of losing his temper, the main reason is Fo Li is somewhat scared of Shangguan Linlang, fearing that she might dislike him.
So those actions which are useless to him, Fo Li obviously won't do them.
