Basically hong ye song kidnaps him bc he tells that he has. Something of his in his inventory which leads to J having to come up with a story to tell him why. I honestly forgot the tiny details but just know this leads hong ye song (not know that it's j under the mask) to be like oh lee sa Young's secretary has the tomato market stone he wanted.

See how Hong Ye Song's eyes are glowing, well it's one of his skills. He can technically see your inventory to a certain extent. So when he cancels the auction, he kidnaps J and they enter a subspace in which he interrogates J of how he got a weapon with his insignia on it. Of course J doesn't know what his talking about, so with HYS's persistence, J took out the only weapon he had, the basilisk sword. Sure enough it has the insignia of HYS, the sword was also responding to HYS recognizing him as its father/creator, but HYS doesn't remember ever creating it. Even J is baffled since he got the sword inside the rift. This gives the clue of how parallel universe exists inside rifts. To shift HYS interest and to keep him quiet, J showed him the magic stone he was eyeing and made a contract with him. all throughout this, LSY was constantly calling J, and when he didn't answer, he started making a scene at the auction. Also I say kidnapped here but as HYS cancelled the auction he throw something at the audience causing the whole place to be filled with smoke, J then saw a ceramic chicken that he followed leading him to HYS.
Can someone spoil me what happens nextt ughhhhhhhhhhh
