Yang Fei pulled out another CD from Japan, "What's this?"
There was no cover on the CD, and Yang Fei couldn't tell what it was.
After thinking for a while, Yang Gang replied, "A documentary CD."
"What kind of documentary?"
"Er, it explores human nature," Yang Gang said.
Yang Fei was surprised, "No way! You, of all people, would watch something as refined as this? This is my favorite kind of thing to watch. Hurry up and put it in the computer, let's play it."
"Er..." Yang Gang hesitated, "I don't think you're quite suitable for this kind of documentary. It's over an hour long."
"Humph!" Yang Fei snatched the CD, "I love watching these kinds of documentaries, I never miss a minute."
"I think this time you can't."
"Psh! Yang Gang, I'll make a bet with you: if I can't watch the entire CD, I'll sleep with you tonight!"
Yang Gang 'gulp' swallowed his saliva, "Okay then."
He took the CD from Yang Fei's hand and inserted it into the computer to play.
A moment later.
