Is the '92 line' actually a faction?

Aren't it just the two of them, Son Heung-min and Lee Jae-sung?
I'm not sure if the '90 and '91 born players like Kim Seung-gyu and Jo Hyeon-woo will join in as well.
The '96 line includes Kim Min-jae, Hwang Hee-chan, Hwang In-beom, Na Sang-ho, Paik Seung-ho, Kim Moon-hwan, and Cho Yu-min.
Since Kim Moon-hwan (born '95) and Paik Seung-ho (born '97) also hang out with them,
the headcount is actually quite large.
