As a friend and fellow artist born in 1988 who has lived through the same era

Jung Hae-in's sincere heart in personally visiting and cheering for Big Bang's 20th anniversary concert is truly heartwarming.

Shining moments holding light sticks together with fans, just like the phrase "My youth, our youth."

You can really feel the strong loyalty and special bond of the '88z in their interaction.
