It started with a little glass that Han Shin brought for Zein. A harmless wine with a low percentage catered to people with a normal constitution like guides and civilians.
"I never drink," Zein said with a frown.
It was easy to understand why--Zein never touch something that would result in him losing consciousness. One could easily imagine what might happen to a guide with a pretty face who couldn't say no or fight back. So he had never touched one, although it might be easier to find a bottle of booze than a bottle of fresh water in the red-zone.
"I know," Han Shin already guessed that might be the case. "But just a little bit is alright, isn't it?"
The guide was in a different environment right now, and Han Shin wanted to show the guide that he was in a safe place. That he didn't have to feel too scared or too cautious of things anymore.
