Liam's facial muscle flinched. The rival feelings between him and Noah were obviously mutual.

Lana creased her forehead and looked at Liam, "It's okay right?"

Then she gave him a look saying, 'Why wouldn't it be okay?'

Liam gave her a smile and nodded. The both of them were business competitors and were considered staunch rivals, but at that moment they had all come for lunch and Lana seemed to like Brione very much. 

So even if he was irritated with Noah, he should still be casual and shouldn't act childish.

Lana on the other hand did not see anything wrong in the siblings joining them for a simple lunch. It was not a big deal… Besides, who knew, they could be good friends out of the business world if they kept meeting informally!

Lana offered the available seat beside her and asked how Brione was doing. The two ladies enjoyed each other's company very much, contrary to the dull and awkward behavior between Noah and Liam with each other.
