Anna's POV:
Radium condom?
I didn't understand why Mark is laughing at, but after a few seconds; I got a flash that Radium will glow in the dark, and I got a flash how it illuminates on Mark, SHHH!!! I can't imagine when Mark put it on and how it lightens up. It's really embarrassing to visualize it, and now I understand why he is laughing, so I immediately threw the box at him. And when I looked at blindfold, Mark immediately said, I gave a good kiss when I am blindfolded, and I totally agree with him, not only I gave a good kiss even I enjoyed his kiss too.
