The Secret Behind "0330"

Going back last March 30,2011 which is the release of “0330″, fans got eager on what the lyrics means specially the phrase “Don’t deny our  r²π.” So some fans unlocked it and here it is for those who are still confused and still doesn’t know about it:
Music critiques and fans are quite confused with the title of the song, or how it was related to the story. However, the release of the music video on March 30, 2011 gave way to unlock the meaning behind the track. Some lines of the track which contributed by AJ were all confusing and many other fans tried to unlock. The famous line from the track is, Don’t deny our r²π… . Everybody knows that r²π is a mathematical formula to calculate the area of a circle. In Egypt during the primitive years, a circle was considered as one of the symbols for eternity, because it has no beginning and has no end. So when the word circle is used in the context of love, it would represent an eternal love. Hence, the line means Don’t deny our eternal love….
.
However, some interpretations are as follows, a formula of pi represents the number 3.14, that if the decimal point is removed, it will be the scrambled number for 143, which means I love you.
.
According to the boys on Twitter, 0330 implies that the song is best when listened to at 3:30am. It also stands for 30 March which is the date of release of the album and their comeback.
.
Other explanations take on 0330, that the “0″ which is a circle represents eternal love. The number “3″ represents wholeness, holiness (like the Holy Trinity), and in the Pythagorean, “3″ means completion. To conclude, 0330 means eternal, whole and complete love.
.
Another way to interpret the title, 0330 goes that when you flip the first 3, it would result to “080″. The number “8″ symbolizes new beginnings. A new beginning for the group since they recently changed two members. “0″ symbolizes eternity like r²π. The lyrics don’t mention 0330 at all, so the fans think that the lyric “r²π” may be the only link between song and title. To date, there has been no confirmation from any members of U-KISS, the real meaning behind the lyrics.
