A-ssi, who attended the legal consulting meeting, said in a phone call with Kukmin Ilbo, "Daesung visited a law firm on September 20th, 2017 to ask whether he'd be responsible should a building he's about to purchase be caught for illegal businesses." He bought the building two months later in November. "Before the purchase, Daesung worked with a real estate agent, a bank agent, and a law firm for consulting and asked about things like the legal implications of abetting prostitution. At the time, Daesung was aware of the illegal businesses and where they were operating in his building. He definitely knew that there was an illegal business in the building." A also remembered that Daesung had asked whether he'd be able to kick out an illegal business owner to which his legal team had responded that the building owner is not able to in a one-sided manner.
