Tang Wan went back and mentioned this to Jiang Jinsang.
The final conclusion is:
[Fourth Brother's family is missing a manager.]
Jiang Jinsang looked at her with a smile, "Is this your way of urging marriage?"
"He does need someone to manage things. Third Brother has been staying at the lab a lot lately, don't you think Fourth Brother is back to his old ways, with day and night reversed?" Tang Wan pursed her lips, "But this time he gave too much money, maybe invite him over for dinner sometime?"
Jiang Jinsang raised an eyebrow: Invite him again?
The last time he came over, he served him medicine, and took away his own set of clothes, never mentioning when he'd return them.
He just laughed, "Consider it extra for our kid's milk money."
"..."
Tang Wan didn't listen to Jiang Jinsang, and still called Jiang Chengsi over the weekend to invite him for dinner.
But since his club's renovation is nearly complete, and he's busy moving, he really doesn't have time.
