Spies, secrets and slow-burn romance make for a powerful opening act. On October 10, tvN’s new drama *100 Days of Deception* kicked off with ratings that no other tvN weekend drama has matched this year.

## 100 Days of Deception: The Premiere Numbers

According to Nielsen Korea, the first episode averaged a 5.3 percent nationwide rating. That’s the highest premiere rating of any tvN Saturday-Sunday drama in 2026, and it made the show the most-watched cable program of any kind on Saturday. The spy romance stars Kim You Jung and GOT7’s Park Jinyoung.

## Saturday Ratings Snapshot

| Drama | Network | Nationwide rating |
| --- | --- | --- |
| **Doctor X** (Ep. 2) | SBS | 14.9% |
| **Love on the Menu** | KBS 2TV | 14.7% |
| **100 Days of Deception** (Ep. 1) | tvN | 5.3% |
| **A Love Other Than Yours** (mid-run finale) | KBS 2TV | 2.3% |
| **Fly High Butterfly** | JTBC | 1.7% |
| **Dive into You** (Ep. 5) | Channel A | 0.3% |

## Why 5.3% Is a Big Deal?

Cable dramas usually pull lower numbers than terrestrial broadcasters, so a 5.3 percent premiere is a strong sign for [tvN](https://en.wikipedia.org/wiki/TvN_(South_Korean_TV_channel)). Beating every other tvN weekend premiere this year suggests the pairing of Kim You Jung and Park Jinyoung, plus the spy-romance premise, has plenty of curiosity behind it. The real test, as always, is whether episode two holds or grows.

## The Competition

Terrestrial TV still dominated the night. SBS’s new medical noir *Doctor X* rose significantly for its second episode and became Saturday’s most-watched program overall at 14.9 percent. KBS 2TV’s *Love on the Menu* landed a close second at 14.7 percent.

## Other Dramas on the Board

KBS 2TV’s *A Love Other Than Yours* wrapped up the first half of its run at 2.3 percent. Meanwhile, JTBC’s *Fly High Butterfly* rose to 1.7 percent for the night, and Channel A’s *Dive into You* earned 0.3 percent for its fifth episode.

## What to Watch Next Weekend?

Keep an eye on three things:

- **Retention:** Does *100 Days of Deception* stay above 5 percent in its second episode?
- **The ratings race:** Can it narrow the gap with the 14 percent shows?
- **Word of mouth:** Spy romances often build through twists, so growth is possible.

We’ll update this post when the next ratings arrive.
