A bit confused

I'm pretty sure he drugged it

From what I remember, he dropped some pills inside the bottle, not sure for what purpose, though.

I think a few chapters ago, when he asked the guy to buy him cigarettes, he used it to see how long it took the guy to leave the room, go out and buy them and come back, to get an idea of how far or not he is from the outside.

Tell time or drugged water

For me it's to tell the time.. ╮(￣▽￣)╭

i think he put sleeping pills. a few chapters ago he said that if he put him to sleep he can get the keys out of him

true, he said that, but he also said that there were no sleeping pills in the first aid kit in the room and was irritated that the guy had thought of even that, so I don't think he drugged the water

It's water and milk and it's a timer no drug here.

how do you tell time by milk and water?? im curious xD

But remember he said that there are no sleeping pills?! (￣∇￣")

I thought Dohun put water there so that he could see when Sungho comes back (the water starts vibrating a little, barely noticeable, but enough to understand)...

Oh, I meant to reply to thee very first comment in thus thread.

For a minute there... I was confused. (⊙…⊙ )

It's a time...Here's how he used it:
