If they could not prevent the wormhole from opening, they had no other choice but to respond only after they checked what was coming out of it. That would be the only way for them to find out the truth of this mystery.
"Oh, you are here!"
Sitting in his office chair, Sangoon waved at Sungwoo.
Sungwoo asked, "Did you get a response when I wasn't here?"
Sangoon nodded, then said, "It was nothing. They just pushed me to bring you over here as soon as possible because there were only 5 hours left."
I didn't know who they were, but it was clear that they wanted to meet Sungwoo.
Why?
"Oh, I think I heard a meaningful message from them that we should prepare for war, but since I heard it between sleep and wake, I was not sure if they would fight against us, or join hands with us together."
Fighting?
Sungwoo and his allies were always prepared for a battle, so their problem was who would be their opponent.
