OMG

The song begins with an admission that the lyrics are dedicated to a beloved, immediately setting a personal and exclusive tone. As NewJeans' members Haerin, Minji, and Danielle sing about moments of vulnerability and exhaustion, they highlight the pivotal role the love interest plays in lifting their spirits ('It's you, 날 걱정하네, it's you, 날 웃게하네'). The love they experience is not just a fleeting emotion, but a deep connection that rejuvenates and encourages them. This sense of security and joy in another's presence marks the start of an emotional journey filled with adoration and gratefulness.

The pre-chorus and chorus provide a broader context to this story, with the repeated question, 'Who is he?' hinting at external curiosity about the identity of this significant other. Despite the queries, what matters to the protagonist is the consistent support they receive from their partner, who appears without fail ('바쁜 척도 없이 넌 나타나'). The chorus uses the phrase 'Oh my God' as a jubilant exclamation of amazement and contentment that this individual is truly there for them, reinforcing the theme of unwavering commitment. Each repeated refrain of 'Oh my God' underlines the depth of their incredulous joy at finding such a perfect confidant and companion.

Throughout the song, there is a sense of contented reliance in the context of the relationship. The lyrics paint a picture of a protagonist who has found their other half, someone who completes their day ('너만 생각나, twenty-four'). There's a transformation in their life since meeting this person, suggesting that life was insignificant before this relationship filled it with endless meaning ('널 알기 전까지는 나 / 의미 없었어 전부 다'). The sentiment that this person occupies a central, continuous place in their life is powerful, with the love interest being described as someone living within their 'system,' almost as if they are an essential part of their being.

The bridge and post-chorus create an imagery of a glowing heart, symbolizing the overwhelming, almost incandescent happiness that love has brought into their life ('My heart is glowing, it's glowing'). As the song progresses, their declaration of never letting the person go and the inability to sleep due to the heart's luminescence showcase a mix of peaceful contentment and exhilarating excitement. The sense of joy is so overwhelming that it borders on madness, a coveted madness that only true love can incite.
