jian wasn't even embarrassed in the car during the petting .. let is say ...he was fucked on the bar stool in front of everyone before... So he is not a shy person.
In that bar everybody gets fcked publicly lol And he aslo had the same drug that Mieum got, so he knows how it is (remember when Jitae and Hajoon were in the bar talking, and Jian appeared full horny, wanting to have sex with anyone (first Hajoon, then secretary Jin)
