The normal thing to do, after Jiang Muwan introduced Mei Qiong to Gu Jiangnian, would have been to then introduce Gu Jiangnian.
But she didn't.
As a result, Mei Qiong's address of 'sir' seemed a bit awkward.
Upon hearing this, Gu Jiangnian smiled lightly. He nodded at Mei Qiong's response, "Miss Mei has a fine eye. It's precisely for this reason that Miss Jiang and I are standing here together."
Jiang Muwan: ....
Mei Qiong: ......
Gu Jiangnian's underlying message might as well have been as blunt as telling Mei Qiong: Young lady, not bad, you're not blind.
Normally standing taller than the two, Jiang Muwan slightly lowered her head in that moment, a hint of irrepressible mirth fluttering across her eyes.
And the hand Gu Jiangnian had on her waist tapped gently, signaling her to pull herself together a bit.
Mei Qiong's words got caught in her throat, seemingly not expecting Gu Jiangnian to play out of turn.
