SOHEE noticed that the beer Ho Changmin handed to him tasted a bit strange.
Hence, he just pretended to drink it.
He was naturally suspicious of people he didn't know that well since he had bad experiences in some of his previous part-time jobs. There were a few customers who tried to drug his drink when he was working as a bartender before, and a few who tried to spike his drink when he was at a dinner party.
So, of course, he would be wary of a stranger offering him a drink.
But I got curious, so I still accepted the drink Ho Changmin offered.
When Sohee was sure that the beer was tampered with, he pretended to fall asleep while Ho Changmin was in the bathroom.
He got suspicious when the kid stayed in the bathroom for that long.
It was as if Ho Changmin was waiting for something— like for the drug to take effect.
Hence, Sohee pretended to have fallen asleep.
Lo and behold, Ho Changmin showed his true color then.
