A few moments ago, Young-Gon wanted to shame Jung for being a two-timer, but given the opportunity he gloats of being one himself...
In this chapter, our trio - Zhang "Follows look" Bora, Kwon "Follows taste" Eun-Taek and Hong "Just follows" Sul - seem to be guilty of the same train of thoughts towards Yoo "Follows Hong" Jung.
It is as if, for some reason, everyone was expecting Jung to be leagues above a normal human being. Like never cheat. Or never be wrong. Or not be a psychopath.
I think it's sometimes possible to expect too much out of somebody, and that's ain't roight.
