20cm

TOMORROW X TOGETHER, commonly known as TXT, is a South Korean boy band known for their youthful and energetic music that often resonates with the experiences of adolescence. '20cm' is a song that captures the bittersweet nature of growing up, particularly the changes that come with puberty and how they affect a close friendship that may be blossoming into something more.

The lyrics of '20cm' describe the physical changes experienced by a young person, such as a sudden increase in height and a deepening voice. These changes are not only physical but also emotional, as the protagonist feels a growing distance ('20cm') between themselves and a friend they have known since childhood. The song uses the metaphor of physical growth to represent the emotional maturation and the evolving feelings towards the friend. The protagonist is awkward about these changes, feeling out of place in their own body and unsure about how to act around their friend now that their feelings are changing.

The song also touches on the desire to be closer to the friend, to understand them on a deeper level, and to be there for them in every way possible. The protagonist expresses a longing to bridge the gap that has formed, not just in physical height but in emotional connection. The mention of wanting to reach the top shelf in the library for them or being on their side like a loyal member of a tteokbokki (a popular Korean dish) team illustrates a yearning to be supportive and present. The song ends with a tentative question, asking if it's okay to close the distance, symbolizing the protagonist's wish to take their relationship to the next level.
