Choi "DanDy" In-kyu initially made his debut in Azubu The Champions Spring 2012 under the name "YaNgSin" as the support player for SuperStar. The team managed to win a game against NEB but they still failed to make it through groups. SuperStar disbanded a short time later and YaNgSin joined MVP White as a jungler under the name "Ingoo".
Ozone began the new year with PANDORA.TV Champions Winter 2013-2014 where they managed to make it to the finals but were swept by the undefeated SKT K to end in second place overall. They placed similarly at HOT6iX Champions Spring 2014, losing 3-1 to Blue in the semis but beating Blaze 3-2 in the third place match to finish in third. A month later, Ozone changed their name to Samsung White. HOT6iX Champions Summer 2014 was not much different for the team. They lost 3-1 again to Blue in the semis but they managed to sweep SK Telecom T1 S in the third place match. They were forced to play a tiebreaker against SKT K for the second Korean seed at the 2014 Season World Championship and they managed to sweep them 3-0 for the spot. White came into worlds as the heavy favorites and impressed, only dropping two games the whole tournament. They played a fairly one-sided final against Star Horn Royal Club and took the title with a 3-1 victory. On October 31st 2014, DanDy announced his departure from Samsung White. On November 27th, 2014, DanDy, Skatch, Heart and Mata all together joined Vici Stand Gaming.
