If they weren't familiar with each other, Lu Tianjun wouldn't be so relaxed around Jiang Xiaoyue, and Jiang Xiaoyue would feel the same.
Although Jiang Xiaoyue has a forthright personality and often speaks her mind, with a kind of heroic aura about her, she is actually very measured in how she conducts herself. Unless you're a particularly good friend, her smile wouldn't be so radiant.
As for Lu Tianjun, there's even less need to mention it. Due to his family's reasons, he rarely extends trust to strangers.
At present, the only people he opens his heart to are Father Lu, Lu Jiang, Feng Qingxue, and Guan Cheng. The younger ones: Lu Tianzhi, Guan Yu and Feng Qingyun receive his care but don't understand Lu Tianjun's thoughts.
Although he and Jiang Xiaoyue don't behave intimately with each other, one can tell they are particularly close friends just by looking at them.
