i think since beginning because his security detail let him know when yujins dad got out of prison. My theory is that when he was kidnapped by him he heard yujin singing and developed ptsd where only that calms him down and he needs yujin to be with him. But now its become less about possession and more about love. I just wish he would tell yujin that he knows abt his dad bc hes been feeling so guilty :(

WHEN DID HE KNOW? FROM THE BEGINNING?
