When YuWon returned to the base, two days had passed in the real world. He didn't think it was a big deal until he stepped through the gates.
"There he is!"
"Took you long enough!"
"We thought you got lost or something!"
Strange faces greeted him like they had known YuWon all his life. At first, he got startled. But then he realized the reception he was getting was probably because he had saved them from the worms during the first trial.
He just smiled and carried ahead, with Lysandra clinging to him like a newlywed wife.
I can't say that isn't the case.
Before returning to the real world, Lysandra had wanted something from him. YuWon agreed without a second thought and only then she showed him an altar.
Lysandra smiled giddily and dragged him to the altar where they got married, with nature as their only witness. Hell, they were even wearing identical rings made of vines.
