Our Joyful Good Day reaches a turning point in Episode 120 as Go Dae-chi's confession sends shockwaves through Kangsu Construction and both families. Fair warning: spoilers follow for the fallout from his surrender and the emergency board meetings. Instead of flamboyant corporate attire, this episode anchors the dramatic tension in practical, restrained daily wardrobe choices. Jo Eun-ae steps forward in clean layered shirting that feels approachable yet composed, while Go Gyeol relies on sturdy collared button-downs to manage the brewing crisis. Here is a closer look at the key silhouettes from Episode 120, how to style these structured pieces for your own rotation, and what similar pieces can help you capture the aesthetic.
Jo Eun-ae's Layered Collared Shirt and Structured Vest
Jo Eun-ae opts for quiet restraint during her visit to the memorial hall, layering a neat grey button-down shirt beneath a deep navy sleeveless vest. The pointed collar stays flat against the crew neckline of the knit top, giving her look a crisp, tailored frame without feeling stiff. Carrying a canvas strap bag over her shoulder, the styling stays grounded and practical.
For an everyday casual or business-casual setup, layering a fitted button-down under a knit or tailored vest creates clean visual lines. It draws attention upward toward the face and gives smaller frames balanced definition without adding heavy volume across the shoulders.

Meanwhile, Go Dae-chi sits in a classic black single-breasted suit jacket, crisp white dress shirt, and black necktie—the ultimate uniform of formal reckoning.
