Summer Rain

At its core, Summer Rain is a beautifully constructed metaphor exploring the dual nature of love—its breathtaking arrival and its devastatingly quick departure. The song uses the unpredictable phenomenon of a sudden summer downpour (often referred to as a sun shower) to represent a romantic relationship that catches a person completely off guard. Just as summer rain provides relief from the heat but can also leave one drenched and cold, the love described in the song brings both brilliant joy and inevitable sorrow. The lyrics convey a narrative of someone looking back on a past relationship that, while fleeting, left a permanent mark on their life.

The central message is one of acceptance and bittersweet gratitude. Rather than expressing anger over the relationship's end, the narrator chooses to cherish the "brilliantly shining time" they shared. The song beautifully captures the vulnerability of opening one's heart, illustrated by the imagery of sharing a small umbrella and the sensory memories triggered by the scent of wet earth and grass. By comparing their shared history to a "transparent story" and the tears falling from the sky, the song highlights how intertwined human emotions are with the natural world. The use of the rainbow metaphor specifically underlines the human desire to hold onto beautiful moments, even when we know they are inherently transient.

The narrative of the song unfolds as a poignant reflection on a sudden, overwhelming romance, comparing the arrival of love to an unexpected summer downpour. The narrator begins by reminiscing about a love that caught them completely off guard, much like the sudden summer rain that everyone experiences at least once in their lifetime. This love was so profound and consuming that the mere sound of the rain outside was enough to keep them awake at night, their thoughts entirely occupied by this person. As the rain falls, it brings forth the deep, earthy scent of the wet ground, which the narrator metaphorically links to their own trembling, overflowing emotions. They vividly recall the heart-fluttering moments, such as the nervous anticipation of sharing a small umbrella, wondering if this beautiful encounter was nothing short of a summer day's miracle.

As the story progresses, the narrator acknowledges the unpredictability of their shared future. They describe their romance as a passing sun shower—beautiful but fleeting. Despite their deepest wishes, they continually missed each other, moving in different directions like the wind. There is a heartfelt plea embedded in the memories, asking the lover not to disappear as quickly as a rainbow that briefly paints the sky after the rain clears. The sensory imagery shifts from the scent of earth to the scent of wet grass, symbolizing the lingering nature of their feelings even as the relationship stands at a confusing crossroads, obscured even by the light of the moon.

In the final reflections, the narrator looks back with a sense of profound gratitude rather than bitter regret. They describe the relationship as a brilliantly shining time in their life, thanking their partner for being as clear and refreshing as the summer rain. The memories, though compared to tears falling from the sky, are cherished. The joy and the sorrow intertwined in those summer days remain as a transparent, crystal-clear story—a beautiful stream of rainwater that once nourished their soul and will be remembered forever.

Summer Rain (Korean: 여름비) was released on September 13, 2017, serving as the lead single for Rainbow, the repackaged edition of GFRIEND's fifth extended play, Parallel. The track was brought to life by the acclaimed South Korean production duo Iggy and Youngbae (Seo Yongbae), who were the masterminds behind many of GFRIEND's early signature hits, helping to define the group's distinct musical identity.

The creation of the song is particularly notable for its brilliant interpolation of classical music. The producers boldly sampled "Im wunderschönen Monat Mai" (In the beautifully shining month of May), the first movement of Robert Schumann's renowned 1840 song cycle Dichterliebe (A Poet's Love) Op. 48. This classical piano motif was seamlessly interlaced with a rhythmic 90s New Jack Swing beat and GFRIEND's characteristic twinkling synthesizers. This inventive fusion was designed to maximize the group's unique emotional sensitivity, creating a sonic bridge between the lively energy of summer and the approaching melancholic aesthetic of autumn. The recording process involved intricate string arrangements by Kwon Seokhong and performances by Jungstring, elevating the track's baroque-pop grandeur.

The rhythmic structure of Summer Rain thrives on the interplay between classical fluidity and modern pop strictness. The song is set in a 4/4 time signature with a tempo of 104 beats per minute. The foundational piano sample plays with a flowing, romantic rubato feel, but it is tightly quantized over a crisp, rhythmic New Jack Swing drumbeat. This creates a compelling push-and-pull effect—the melody wants to linger in the past, while the rhythm forcefully drives the song forward.

Lyrically, the rhyme scheme follows traditional Korean pop structures, utilizing terminal rhymes centered around polite verb conjugations. The repeated use of the sounds "~jyo" (죠) and "~yo" (요) at the end of lines establishes a comforting, rhythmic lullaby effect. This consistent end-rhyme creates a sense of continuous flow, mimicking the steady patter of raindrops falling. The internal rhythm of the syllables is meticulously crafted to match the twinkling synths, allowing the vocalists to deliver the heartbreaking lyrics with a smooth, gliding cadence.

Musically, Summer Rain is a masterclass in blending disparate genres to evoke a specific emotional landscape. The song employs a Baroque-pop and New Jack Swing crossover. The most prominent stylistic choice is the sampling of Schumann's classical piano, which grounds the song in a traditional, romantic melancholy. This classical foundation is juxtaposed with a propulsive, 104 BPM syncopated drum loop. This contrast creates a signature K-pop trope often associated with GFRIEND: dancing while crying, where the upbeat rhythm masks a deeply sad lyrical core.

Literarily, the song relies heavily on similes and sensory imagery. Phrases like "like a passing sun shower" and "like a clear summer rain" create a gentle, poetic tone. The songwriters also use polite, formal Korean sentence endings (e.g., -yo and -jyo), which gives the narrator's voice a sense of respectful distance, as if they are carefully addressing a cherished memory or writing a heartfelt letter to a past lover. The vocal delivery is notably soft and breathy in the verses, gradually building to a powerful, belting chorus that mirrors the dynamic swelling of a rainstorm.

Upon its release, Summer Rain performed well commercially, peaking at number 11 on the South Korean Gaon Digital Chart and debuting at number 30 on the Billboard Korea Kpop Hot 100. It also earned GFRIEND music show trophies, including a first-place win on M! Countdown. The music video, which beautifully incorporated ballet elements into the choreography, received praise for its elegant and slightly more mature aesthetic compared to their previous school-uniform concepts.

The song's ingenious sampling of Robert Schumann's Dichterliebe drew praise from critics for introducing classical music elements to a K-pop audience, demonstrating how 19th-century romanticism could flawlessly blend with a propulsive dance beat. In the context of GFRIEND's discography, Summer Rain acts as a critical piece that solidified their "passionate melancholy" concept. Long after the group's disbandment, the song remains a beloved cult favorite among fans, often cited as one of the most lyrically beautiful tracks in their catalog.

The lyrics of Summer Rain are rich with natural imagery and weather-related metaphors that perfectly articulate the nuances of a fleeting romance.

• The Summer Rain / Sun Shower (여름비 / 여우비): The rain is the central allegory for sudden love. A sun shower is notoriously unpredictable and brief; similarly, the love the narrator experienced arrived without warning and left just as quickly.
• The Scent of Earth and Grass (흙내음 / 풀내음): These olfactory metaphors represent the deep, organic, and grounding nature of the narrator's emotions. Just as rain brings out the rich scent of the soil, love brings forth the narrator's deepest, most hidden feelings, making the memories sensory and permanent.
• The Rainbow (무지개): In the lyric "Don't stay short like a rainbow after the rain stops," the rainbow is a metaphor for the lover's presence. It represents something breathtakingly beautiful but tragically ephemeral.
• Tears from the Sky (하늘에서 내린 눈물): The rain is personified as the sky crying, mirroring the narrator's own internal grief over the end of the relationship, blending the environment with their emotional state.

Several key motifs anchor the song's emotional and structural narrative. The phrase "Like the summer rain" (여름비처럼) acts as the central lyrical hook, returning multiple times to remind the listener of the song's core metaphor of unpredictable love. Another crucial recurring line is "It was a time that shone brilliantly" (찬란하게 빛나던 시간이었다고), which serves as the emotional thesis of the song—affirming that despite the pain of separation, the love was a profoundly beautiful experience worth remembering.

Musically, the Schumann piano sample is a recurring motif that opens the track, appears during the instrumental breaks, and closes the song. Its repetition acts as a sonic memory trigger, plunging the listener back into the classical, melancholic atmosphere whenever the modern beat subsides. Additionally, the phrase "My emotions soaked in the scent of..." repeats with slight variations (first earth, then grass), marking the progression of the rainstorm and the deepening of the narrator's emotional saturation.
