Wen Yan, Ruan Yu, speaking of these two names separately, one wouldn't think there's anything noteworthy.
But if you put them together, encountering them at the same time, there's an issue, as it clearly becomes a play on the phrase "soft and gentle words."
It would be too much of a coincidence for their names to match so well unless their parents were the best of friends, and they themselves had been childhood sweethearts born at the same time. That would be somewhat believable.
But it was obvious that "Ruan Yu" was younger, clearly not of the same age as "Wen Yan."
Even if the girl looked young for her age, her behavior towards the man was also off.
That kind of spontaneous respect and compliance was not of an equal but rather that of a maidservant.
There wasn't a hint of the familiarity you'd expect from childhood sweethearts.
