Who is the sunbae among Shinhwa and Lee Hyori?

Shinhwa vs. Lee Hyori: Who is the sunbae out of these two veteran artists? 

These legends met backstage at music shows last week to finally clear up the confusion on who is the sunbae. At first, Shinhwa greets Lee Hyori and calls her, "sunbaenim", and Lee Hyori hilariously acts her part with her natural charisma. But in the next scenario, Lee Hyori becomes the humble artist in front of Shinhwa who do rock-paper-scissors to figure out which member gets to keep Hyori's CD, album cover, and Hyori herself! Minwoo ends up winning the round to keep Hyori for himself and the two almost enact a brief make out scene, bringing laughs.

Shinhwa made their debut back in March 24, 1998 while Hyori made her debut on May 12, 1998 as part of Fin.K.L, making Shinhwa Lee Hyori's sunbae by two months.

So if you guessed Shinhwa, pat yourself on the back because you guessed right!
