Mei Shu nodded as a matter of course, "His mental age is younger than yours, so you are his big brother!"
Only now did Mei Yan react.
This man wasn't pretending to be stupid; he was really that clueless!
In an instant, the disgusted look he had when he glanced at Lu Si turned into one of pity. He even took the initiative to grab a tissue and help him clean the rice grains that had fallen on his suit. "Chew your food slowly. Don't make a mess."
Lu Si stared blankly and listened obediently, stealing a glance at Mei Shu's expression. He then nodded docilely and said, "Okay."
Mei Shu couldn't help but mess up Mei Yan's hair playfully as she watched Mei Yan intentionally adopt a mature demeanor. "I didn't expect you to be such a good big brother, Yanyan. You're amazing!"
Mei Yan allowed her to touch his hair, and when she was satisfied, he straightened his hair with a straight face and asked, "So, sister, where did you find him?"
