May OST Collection: From Tear‑Jerker Ballads to Hype Anthems
A Curated Guide to May's Essential OST Performances
For the first four months, I kept things loose and mostly just listed all the OSTs that stood out to me, but starting this month, I’m giving the series a bit more shape by organizing each track into one of four pillars so the reviews feel more focused and easier to follow.
Every month I’ll sort the newest K‑drama OST drops into four buckets:
the tear‑jerkers,
the feel‑good romance tracks,
the moody atmospheric cuts,
and the full‑blown hype songs.
It’s fun way to make sense of how each track works inside its drama but also to help you find the types of songs you gravitate towards more easily. Here’s where the releases landed for me this month. Also, the KPOPS! soundtrack was such a fun addition to the regular Korean OST fare this month.
Hope you enjoy the update!
The Emotional Power Ballad (The Tear-Jerker)
So Soo Bin ~ Perfect Crown Part. 7
So Soo Bin’s “My Favorite Part” feels like someone quietly opening their heart, the acoustic guitar giving his mellow voice all the room it needs to land with real sincerity. It’s a soft, steady ballad that treats love and devotion as something warm and lived‑in.
Cha Hakyeon (N) & gongwon ~ Absolute Value of Romance, Part 3
“Why the Night” floats on a calm, dreamy melody that lets N and gongwon’s delicate vocals trace the slow rise of hidden emotions. The duet turns confession into something tender and inevitable, like truth finally finding its way to the surface.
Hong Jiyun ~ Recipe for Love, Pt.8
Hong Jiyun’s “Find Rest in Me” moves with a warm, steady glow, shaped by piano, gentle strings, and a vocal tone that feels like it’s offering you a place to breathe. The arrangement expands just enough to feel enveloping, creating a moment of relief that settles in like emotional shelter.
Sam Kim ~ Perfect Crown Part. 9
Sam Kim’s “If You Were My World” already felt tender to me on first listen after hearing that little preview on IU’s Mini Palette. The opening acoustic guitar line lands with a warm familiarity that immediately made me smile, and his voice follows with an easy sincerity that feels like he’s letting something slip rather than trying to impress. The arrangement stays restrained and breathable, letting soft harmonies drift in just enough to deepen the moment without breaking its simplicity.
Jang Minho ~ Recipe for Love, Pt.9
“Just One” carries that soft, familiar ache right from the first line, Minho’s voice warming the melody before lifting into something more exposed. Strings, piano, and a gentle rise of percussion frame that shift, letting the song bloom into a quiet confession shaped by longing, nostalgia and hope.
Doyoung ~ Filing for Love, Pt.4
Doyoung’s “Listen To My Soul” hits me with that soft, exposed clarity where his voice feels like it’s reaching straight for the part of me that wants to be understood. The gentle piano and drifting strings leave so much open space that the emotion lands without effort, turning the song into a quiet moment of honesty I can feel in my chest.
Gummy ~ Sold Out On You Part 9
GUMMY pulls me right in, her voice sitting so close it feels like she’s talking through a memory I didn’t realize I was still holding. The piano and strings wrap around her in this gentle, aching way, turning everyday longing into something that quietly shapes the whole mood of a day.
Byeon Wooseok ~ Perfect Crown Part. 11
“Fate Line” opens with this gentle certainty, Wooseok’s voice settling into the piano like he’s tracing a feeling that’s already lived in him for a while. As the strings unfurl around that warmth, the arrangement leans into inevitability, pulling you into its gravity with a tenderness that feels almost accidental.
Young K (DAY6) ~ My Royal Nemesis, Pt. 2
The moment “Season of Us” begins, the piano and soft synth glow pull me into this quiet emotional tide that keeps deepening as the song opens up. The arrangement gives every breath of the vocal room to bloom, turning the whole track into a lingering meditation on longing, presence, and the kind of love that feels like it’s been waiting for you all along.
Gwyn Dorado ~ My Royal Nemesis, Pt. 3
“Letting Go of My Heart” opens up in a way that feels almost disarming, especially when the piano and strings move together like they’re trying to steady a fragile truth. I felt the shift in my chest when the vocal crested over that arrangement, as if the music was gently teaching me how to loosen my grip on something I didn’t realize I was still holding.
The Upbeat Romantic Theme (The “Feel Good” Song)
Anton (RIIZE) ~ Yumi’s Cells 3, Pt. 5
“Close to Me” opens with a soft guitar line that feels like a secret slipping out, and Anton’s delicate vocal makes that closeness feel even more inevitable. As the arrangement slowly widens with pads, strings, and a gentle pulse, the song turns into a quiet emotional confession, the kind that closes the distance before either person says a word.
BOL4 ~ Sold Out On You Part 6
“Someday” hits me with that familiar BOL4 warmth. The acoustic guitar keeps things moving with an easy, breezy rhythm, and the little sparkles of percussion and synths open the arrangement just enough to feel like something is blooming. When the chorus widens, I can feel that shift from shy hope to real courage.
Nayeon (TWICE) ~ Sold Out On You Part 7
“Love Is Enough” lets Nayeon pour her voice into a soft, glowing space where the piano and strings feel like they’re breathing with her. I hear her move from a near‑whisper to a full, open chorus, turning the idea that love can carry two people forward into something that feels real enough to hold.
Song Hayoung (fromis_9) ~ Youth of Revelation Webtoon
Song Hayoung’s “Love Story” lingers with this soft, steady glow, her voice floating over airy electric‑piano‑style synths that shimmer lightly around a heartbeat‑like bass line and make the whole confession feel alive under your skin. The minimal arrangement keeps everything open and tender, letting her bright, hushed delivery turn vulnerability into something quietly brave.
Heize ~ Sold Out On You Part 8
Heize’s “I see you” wraps itself around me with its gentle guitar pulse and soft piano glow, letting her deeper, tender tone rise in a way that feels like emotional eye contact made through sound. The minimal arrangement keeps everything close and warm, so the song lingers like a quiet confession, the kind you only share when love feels steady enough to hold it.
Punch ~ Sold Out On You Part 11
“Beautiful Days, Lovely Eyes” unfolds like a gentle confession wrapped in acoustic warmth, with soft guitar strums and light whistling creating an airy backdrop that keeps her voice centered. The simplicity of the arrangement highlights the delicacy and sincerity in her voice.
Corbyn Besson & Joshua (SEVENTEEN) ~ K-POPS! movie
“One More Dance” feels like a soft memory forming in real time, and Corbyn and Joshua blend their voices with this weightless warmth that makes the moment feel suspended. A gentle rhythm keeps everything swaying just enough to make you want to stay inside the feeling a little longer.
The Atmospheric/Moody Theme (The Dramatic Vibe)
hrtz.wav ~ Perfect Crown Part. 8
“You Keep Me Here” leans into a warm, guitar‑driven R&B softness that feels like emotional grounding in real time. Riaan’s husky, steady vocal turns the track into a confession of staying not out of obligation, but because love finally feels like a place to rest.
Choi Yu Ree ~ We Are All Trying Here Part.5
Choi Yu Ree’s “On a Gentle Breeze” drifts on soft guitar, airy pads, and a vocal delivery that feels like it’s exhaling for you. The whole track moves with a quiet lift, offering a small but unmistakable sense of release that settles in before you even realize you needed it.
Im Joongwon ~ Perfect Crown Part. 10
“In Your Orbit” pulls me in with its soft synth glow, and Joongwon’s husky vocals make the whole thing feel like a quiet confession. The arrangement stays spacious and weightless, letting that sense of emotional gravity settle in until the vulnerability feels like a place you want to stay.
Park Hae Soo ~ The Scarecrow, Pt. 2
Park Hae Soo’s “The Forgotten” settles into me like a quiet bruise, his husky vocal laid bare against a minimal folk backdrop that refuses to soften the weight he’s carrying. The sparse guitar and airy mix leave so much emotional space that the regret in his delivery feels almost suspended in the room, lingering long after the last note fades.
Nam Jong ~ My Royal Nemesis, Pt. 1
“Anyway” moves like a quiet confession that slowly gathers weight, built from soft piano, airy synths and a vocal that trembles with hesitation. The space around each phrase lingers just long enough to let the emotion settle, capturing the exact moment when connection slips past every defense anyway.
CRUSH & Anderson .Paak ~ K-POPS! movie
That familiar “Flashing Lights” sample slips in, giving the whole track this dreamy, déjà‑vu shimmer that Crush and Anderson Paak twist into something moodier and more intimate. The way the groove wraps around that loop makes the song feel like it’s drifting through memory and reality at the same time, and I love how the vocals lean into that blur with this cool, late‑night softness.
Soyeon (i-dle) & Anderson .Paak ~ K-POPS! movie
"International" walks in like it already owns the room, and Soyeon’s sharp delivery snaps perfectly against that stylish, global‑leaning groove. The production keeps shifting in these subtle, rhythmic layers that catch the light differently each time, giving her vocals something dynamic to push against and turning the whole track into this cool, self‑assured flex.
The Epic/Intense Plot Driver (The Hype Song)
Wanna One ~ WANNA ONE GO : Back to Base
“WE WANNA GO” pulls me in with this bright, rising sweep that feels like someone flipping on the lights in a room you didn’t realize you’d been missing. As Wanna One’s harmonies settle in, there’s this instinctive ease to the way their voices lock together, and the arrangement gives them just enough space to breathe while still carrying that forward‑moving pulse. It’s a cute song intentionally built for togetherness.
DEAN & Anderson .Paak ~ K-POPS! movie
Dean and Anderson .Paak’s “Aftertaste” hits with a rush of R&B smoothness and playful grit, the kind that locks in the moment the drums land. Their voices ride the airy synths and bass with an easy confidence, creating a push and pull that leaves a sweetness lingering long after the track fades. It’s this fun sonic flirtation built into the arrangement itself.
NMIXX & Anderson .Paak ~ K-POPS! movie
“Caution” hits differently once you realize how many groups can fake attitude, but NMIXX actually has the vocal muscle to back it up, flipping from cool rap lines to velvety R&B harmonies without breaking a sweat. That range gives the whole track a gritty, grown edge that locks in perfectly with Anderson Paak’s production, and I love how their voices make the song feel sharper and more soulful at the same time.
Hongjoong (ATEEZ), Anderson .Paak & Jay Park ~ K-POPS! movie
“PITC” struts in with a heavy, swaggering groove that feels deliberately messy, and it opens up towards the end once HONGJOONG’s sharp flow cuts through the beat while Jay Park’s smoother tone slides in behind him. Their contrast breaks up the repetition, giving the track a layered depth that makes this party feel bigger, louder, and way more alive than it has any right to be.
LNGSHOT ~ K-POPS! movie
“Fire With Fire” hits with a sharp, aggressive pulse that LNGSHOT drives forward through grit and swagger. Heavy bass and layered percussion give the track a cinematic urgency, while the vocals cut cleanly through the beat to turn resilience into a hype‑charged anthem.
Chung Ha & Anderson .Paak ~ K-POPS! movie
“Bet On U” glows with this bright, rhythmic sweetness that Chung Ha delivers so naturally, and the melody feels like it’s smiling the whole way through. Every little funk‑leaning detail in the arrangement keeps the song grounded while her voice lifts everything into something warm and hopeful.
That wraps up this week’s roundup, and thanks as always for reading!
