Shen Zhaonan casually sized up Su Jin and the Cheng Zheng couple, and from the meal up until now, he had surmised in his heart that the Cheng Zheng couple didn't like this Su Jin at all.
Based on his understanding, he could assert that this Su Jin was likely an impostor, therefore, he naturally couldn't associate himself with this fake illegitimate son.
Even if Su Jin were real, Su Xi was, after all, the eldest daughter of the Su family, and the Su's were currently under her control. His aim now was to form an alliance with the Cheng Zheng couple, not to care about Su Jin who had just returned to the Su family.
He politely declined Su Jin, "Young Master Su is too kind, I have some personal matters this afternoon, and my assistant is here with the car, so there's no need to trouble you."
Su Jin, whose eyes were already small, narrowed them further and then smiled, "Then alright, since President Shen has personal matters, I won't impose any further. Take care, President Shen."
