In the KBS2 weekend drama Sarang-i Onda (사랑이 온다), actor Ha Seok-jin takes on the role of Kim Mu-jin, capturing viewers with his measured charisma and complex emotional journey. While the unfolding family conflicts keep viewers hooked, his wardrobe presents one of the sharpest examples of modern Korean menswear on television.
Kim Mu-jin strikes a clean balance between professional authority and modern ease. Instead of rigid corporate suits with stiff neckties, his outfits revolve around tailored blazers, fine-gauge knit polos, and versatile earthy tones. Here is a breakdown of 7 key pieces from Ha Seok-jin’s outfits in Episodes 13 and 18, along with practical tips to achieve a similar style.
Piece 1: The Glossy Black Open-Collar Shirt (Episode 13)
“겨우 이렇게 끝낼 거면서 왜 만났니?” (Scene dialogue — Episode 13, 36:21)
In this emotionally charged scene, Kim Mu-jin wears a glossy black button-up shirt featuring a smooth surface with subtle light reflection. The shirt is layered under a tailored olive-khaki jacket, with the top buttons left open to soften the crisp cut of the lapels.
Style Breakdown:
- Color: Black with a soft sheen and matte buttons
- Fabric Feel: Smooth and slightly glossy, similar to a cotton-silk blend
- Silhouette: Semi-relaxed fit that avoids clinging while maintaining clean shoulder lines
How to Recreate a Similar Look: Look for a lightweight lyocell, silk-blend, or fine mercerized cotton button-up in solid black. Pair it with an unlined casual jacket and keep the collar unbuttoned for a relaxed smart-casual impression.
Piece 2: The Khaki-Beige Peaked Lapel Blazer (Episode 13)
“무슨 일인데?” (Scene dialogue — Episode 13, 43:15)
The same scene-stealing jacket from Piece 1 gets its own close-up here: a tailored blazer in an earthy khaki-beige tone, finished with bold peaked lapels. The upward sweep of the peaked lapels visually broadens the chest and lends a commanding presence to a neutral seasonal palette.
Style Breakdown:
- Color: Muted khaki-beige with subtle green undertones
- Lapel Detail: Pronounced peaked lapels that add formality to a casual colorway
- Tailoring: Structured shoulders and a tapered waistline for a sharp, confident outline
How to Recreate a Similar Look: Seek a single-breasted blazer in textured hopsack wool or cotton twill in khaki or sand beige. Anchor it with a dark inner top—such as deep charcoal or ink black—to create sharp visual contrast.
Piece 3: The Dark Collared Knit Polo (Episode 13)
“결이가 오늘은 집에 가기 싫다고 나랑 같이 있겠다는데.” (Scene dialogue — Episode 13, 63:37)
During a late-night phone call outdoors, Mu-jin switches to a short-sleeve knit polo in solid black. Fine-gauge knitwear adds understated polish to relaxed evening wear, showing that casual moments can stay thoroughly refined.
Style Breakdown:
- Color: Solid midnight black
- Collar & Placket: Ribbed polo collar with tonal buttons
- Fabric: Fine-gauge knit cotton with subtle stretch and smooth ribbing along the sleeves
How to Recreate a Similar Look: Swap standard cotton t-shirts for a fine-gauge knit polo shirt crafted from supima cotton or high-twist yarn. A structured knit collar stays upright naturally and pairs smoothly with casual trousers or tailored slacks.
Piece 4: The Classic Navy Double-Breasted Blazer (Episode 18)
“나는 끝을 봐야겠다, 규림아.” (Scene dialogue — Episode 18, 01:01)
Opening Episode 18 with dramatic tension, Mu-jin steps into the frame wearing a commanding dark navy double-breasted blazer. The classic six-button arrangement and clean structured lapels reflect his uncompromising stance in this pivotal encounter.
Style Breakdown:
- Color: Deep midnight navy
- Structure: Classic double-breasted button configuration with crisp chest canvassing
- Silhouette: Traditional tailored cut that conveys stability and resolve
How to Recreate a Similar Look: Choose a dark navy double-breasted sport coat in tropical wool or smooth flannel. To keep the look contemporary rather than dated, wear it over a soft knit layer instead of a formal dress shirt and tie.
Piece 5: The Heather Gray Buttoned Knit Layer (Episode 18)
“내가 다치고 네가 다치고 다른 누군가 좀 다치더라도 우리가 어떻게 될지 나는 꼭 끝을 봐야겠어.” (Scene dialogue — Episode 18, 01:11)
Layered under the double-breasted navy blazer in the same scene, this heather gray knit shirt features a clean polo collar and a three-button front placket. The soft, multi-toned gray yarn breaks up the stark formality of dark navy tailoring.
Style Breakdown:
- Color: Heather melange gray
- Design: Soft polo collar with extended button placket
- Texture: Fine-gauge lightweight knit that lays flat beneath structured suiting
How to Recreate a Similar Look: Pick a light-to-medium heather gray long-sleeve knit polo or buttoned henley. The cool gray hue creates a natural bridge between dark navy jackets and charcoal trousers.
Piece 6: The Light Gray Active Zip-Up Jacket (Episode 18)
“아, 그래서 좀 이렇게 차려입고 인사드렸어야 되는데.” (Scene dialogue — Episode 18, 10:08)
Apologizing that he should have dressed up more properly, Mu-jin shows up in a sporty, light gray zip-up windbreaker jacket. In a brief departure from tailored blazers, this look represents a practical Korean weekend athletic outfit.
Style Breakdown:
- Color: Pale stone grey / off-white with dark zip accents
- Cut: Minimalist stand-collar windbreaker with raglan seams
- Base Layer: Dark crewneck performance tee for crisp contrast
How to Recreate a Similar Look: Pair a clean, logo-free lightweight zip-up windbreaker in pale grey with a solid charcoal crewneck base. Keeping the jacket simple and free of oversized graphics maintains a mature, sleek profile.

“죽는 거보다 사는 게 힘든 거구나. 내가 친절하게 알려줄 테니까.” (Scene dialogue — Episode 18, 56:49)
In a tense late-night confrontation in Episode 18, Mu-jin wears a tactile ivory knit polo underneath a relaxed light grey-beige summer blazer. The distinct open-stitch mesh knit texture and contrasting dark buttons offer subtle dimensional interest.

- Collar: Soft polo collar with dark contrasting buttons
How to Recreate a Similar Look: Seek out an open-stitch or waffle-knit polo in cream or ivory. Layer it beneath an unconstructed linen-blend blazer in soft sand or stone grey to master tonal summer tailoring.
The Wardrobe Formula of Kim Mu-jin
Kim Mu-jin’s fashion in Sarang-i Onda succeeds because every outfit serves character and realism. Rather than relying on flashy designer patterns or hyper-formal three-piece suits, his wardrobe relies on three consistent principles:
- Structured Outerwear Paired with Soft Inners: Tailored blazers in peaked and double-breasted cuts provide architectural presence, while fine-gauge knit polos replace rigid dress shirts to keep interactions grounded.
- Cohesive Neutral Palette: Black, midnight navy, khaki-beige, heather gray, and ivory allow versatile mixing across scenes while reflecting his serious, collected temperament.
- Texture Over Graphic Noise: Fine knit ribbing, waffle stitches, peaked lapels, and silk-like finishes add tactile variety without relying on loud logos or busy prints.
