Wait did Taehee hang up on his bro or is he still on the call?

Well, it was kinda obvious to me that there was a time skip. But I don't know for sure.

Oh, yeah this seems possible because Dojin would have greeted Taehwan

Oof i think it's still on

lol, big bro is in for a big shock

I was thinking they had a conversation, big bro told him about the bad guy, then they hung up.
