Dispatch figured out who was Kim Jung Hyun gf at the time of "Time" filming, one of the reason why he's acting like that to Seohyun. Its Seo Yea Ji

Idk how Dispatch got their hands on the text message between them but it seems Seo Yea Ji controlled what Kim Jung Hyun doing on the filming set, forbid him from having skinship during the filming & told him to change the script

“change it without romance & without touching”

From what Dispatch reported she seems so controlling that she even checked how Kim Jung Hyun greets on the set “it’s right not to say hello” and she also checked what Kim Jung Hyun doing on set he sent videos proof to her

KJH: I've been reading the script. I'm not doing anything else.

SYJ: Correct it without romance.

SYJ: You are happy because of me. So make me happier.

KJH: I'm going to read the script.

SYJ: Yes. Fix it well. No touching romance

KJH: Sure
