"I'll let you go now, but you need to behave, okay?"
Fifteen nodded, appearing relaxed.
"Don't worry, I won't easily give up a jade box worth thirty million."
"Great."
Phoebe smiled, reached over with her palm, pulled on the knot's strap, and with a gentle tug, the climbing rope on Fifteen's feet came loose.
Phoebe tied the rope with great skill, not so tight that it restricted movement but with just enough leeway to prevent escape.
Thus, there were no marks on her skin, just a slight redness.
Freed, Fifteen shook her calves, turned her back to him, and let him untie the rope around her hands.
Phoebe raised his hand, supported her shoulder from behind, moved her slightly messed-up long hair from her back, and leaned close to her ear.
"There's no need to untie the rope on your hands. Otherwise, if you don't behave again, I'll have to tie you up again, and that would be troublesome, wouldn't it?"
Fifteen turned her face, giving him a seductive look.
