Lee Seung Gi filed a criminal lawsuit against Hook Entertainment's CEO Kwon Jin Young, as well as former and current directors.

On December 22 KST, Lee Seung Gi's legal representative stated, "Today morning we submitted a legal complaint to the Seoul Central District Prosecutors' Office against former and current directors of Hook Entertainment, including CEO Kwon Jin Young." They added. "A recent report revealed that Hook Entertainment's former and current directors also deceived Lee Seung Gi and defrauded him out of a portion of his advertisement modeling fees. For years, Lee Seung Gi thought ~10% of his advertisement modeling fees were used to pay "agency fees", but in fact, the former and current directors of Hook Entertainment shared this amount with each other. When Lee Seung Gi raised an issue with this, it was only then that Hook Entertainment finally admitted to this fact and paid Lee Seung Gi about 630 million won (~$494,195 USD) in only advertisement fees, not including any music profits, back on December 16 KST."

They added, "The settlement money that Hook Entertainment one-sidedly transferred [to Lee Seung Gi] is dramatically different from the amount that Lee Seung Gi is aware of [as the correct amount]. Therefore, Lee Seung Gi will respond to Hook Entertainment's claims by filing a claim against Hook Entertainment and its related parties for [his] unpaid music profits and damages suffered from their illegal activities."

They ended their statement by saying, "Lee Seung Gi believes that there should be no more victims like himself and as we mentioned earlier, we will file a criminal complaint against Kwon Jin Young, the CEO of Hook Entertainment, as well as the former and current directors. We will do our best to prevent creating any more victims by revealing the truth behind this case during the trial."
