On the December 16th installment of 'Knowing Brothers', Eun Ji Won put it all out there, saying, "We still don't know Lee Jae Jin's phone number." Lee Jae Jin is known for his odd personality as well as for being the brother-in-law of YG Entertainment head Yang Hyun Suk, and it seems he's also quite private.
Lee Soo Geun stated, "Shouldn't the members know your number at least?" Lee Jae Jin finally got to explain himself. He said, "We've done well, and our income is good too. I'm afraid people might ask me to borrow money."
The other Sechskies members then said they never asked Lee Jae Jin for money, and he surprised everyone by saying, "Sechskies isn't a family. This is a business relationship."
