Nan Zhubin smiled at the security guard in front of him.
The sunlight shone on his face, making it hard to say whether the sunlight warmed his smile, or his smile warmed the sunlight.
Unfortunately, this sunny scene did not serve its intended purpose, because the security guard in front of Nan Zhubin was not a female guard.
Luckily, although the guard was male, he was already over forty years old, an age where he wouldn't resent a particularly handsome young man.
An age where one's strength wanes, one's mentality gradually becomes peaceful, and there's no need to compete for masculinity here.
Some middle-aged men even become kindly, influenced by a cognitive distortion science hasn't yet explored, seeing a bit of their younger selves in Nan Zhubin's face, which makes them gentle and kindly.
But alas.
"Beep—buzz, buzz, buzz, buzz..."
