Flu

IU's song 'Flu' uses the metaphor of an illness to describe the overwhelming and often uncontrollable nature of falling in love. The lyrics paint a vivid picture of the physical and emotional symptoms that accompany this experience, likening it to the debilitating effects of a flu. The repeated refrain 'Flu-hu-hu-hu-hu' emphasizes the persistent and inescapable nature of these feelings, much like the symptoms of a flu that linger and disrupt one's daily life.

The song opens with IU describing her symptoms to a doctor, highlighting the physical manifestations of her emotional state: fever, dizziness, and cold sweats. These symptoms are not just physical but also metaphorical, representing the confusion and vulnerability that come with falling in love. The line '믿을 수가 없어 / 오 이런, 바보 같이 또 사랑에 빠져' (I can't believe it / Oh, like a fool, I've fallen in love again) captures the sense of disbelief and self-awareness that often accompanies these intense emotions.

As the song progresses, IU delves deeper into the irony and pain of love. Despite the discomfort and embarrassment ('힐끗힐끗 눈을 맞추면 I'm very embarrassed'), there is an undeniable attraction that spreads like a virus throughout her body. The chorus, with its repetitive 'Flu-hu-hu-hu-hu,' underscores the relentless nature of these feelings, suggesting that love, much like a flu, is something that must be endured until it runs its course. The song's climax, where IU sings about the inevitability of falling in love despite her best efforts to resist ('피할 수가 없어 / 뜻밖의 사고 같이 또 사랑에 빠져'), reinforces the idea that love is an uncontrollable force that can strike unexpectedly and leave one feeling utterly defeated.

'Flu' is a poignant exploration of the highs and lows of love, using the metaphor of illness to convey the intensity and unpredictability of these emotions. IU's emotive delivery and the song's evocative lyrics create a powerful narrative that resonates with anyone who has experienced the tumultuous journey of falling in love.
