both VIP Girl Lipstick & BB Compact CF were announced in Jan-Feb 2009. i am referring to Etude Global
website
but, in descending order of d news, BB Compact was next after the VIP Girl. so, i assummed, VIP Girl was d 1st on screen collaboration between SukkieHye. yeah, as 1st time collab, they were extremely close...
maybe if we digged d news further, both of them cud hv known each other way before d VIP CF? coz according to GS statement in Champagne, after d VIP Girl kiss scene, both of them became closer. In my thoughts, indirectly... they cud hv known each other before it... n became closer after d scene
below news bout SH model for EH
