The main themes involved in the album are about situations that are related to love or trust. Soothing ballads like "You are the one" and "So I" intend to create a positive environment in one's love relationship. Fast tracks with light-hearted melodies like "Miracle" and "Way for love" contain bubblegum pop lyrics with positive views of love and trust. However, fast, rap-influenced dance tracks like "Twins (Knock Out)", "Over", "L.O.V.E", and "Keep in Touch" have negative connotations about love and relationships. For example, in "Over", the lyrics hovers around a confident persistence after a relationship breakup. "L.O.V.E" involves a loss of hope and confidence after love is shattered. Likewise, Super Junior's debut track "Twins (Knock Out)" speaks of self-deception and the indecisive aspects of a man's mind, contrasting the feelings between a man towards love and how he has to decide whether or not he should continue to love or fight with sticking to his own destiny.
