【專輯介紹】：
March marks the end of the school year in Japan, which means it’s also the season of graduation. Kara’s latest Japanese single – their first single of 2013 – is a fun, high-energy take on the season of farewells and new beginnings. The song takes a positive approach to its theme, calling graduation to beginning of a new journey and better days. The single also includes My Boy as B-side track.
