A few moments ago…
"DUDE, you're really going?"
"Of course, I am," Ki Gayoon said while getting up. "I need to save Baekho and Yu Minju. Plus, I need to know why Noh Yuno's siblings want to meet me."
"Are you not going to tell Yuno?" 17 asked. "This concerns him, too."
"It's easier to ask for forgiveness than permission from your lover, you know?"
"Yuno will kill you."
"Well, it's better than letting him put his life at risk again," Ki Gayoon said. "Take care of Noh Yuno in the meantime."
He really didn't want to leave Noh Yuno's side.
But he'd rather go alone and meet those 'siblings' than bring his lover in another dangerous place.
Noh Yuno won't be happy with my decision, but at least, he'll be safe here.
"Fine," 17 said, shaking his head. "But don't forget that I warned you, okay?"
