I may not heard about Rainbow back when I was young since they debut on November 14 2009 I was four years old but I’m very happy for Rainbow because they reunite after three years of their disband because the colors of the Rainbow never loses their true color or being separated because a Rainbow always stick together and be friends forever 🌈🌈❤️❤️🇰🇷🇰🇷🎂🎂
