April 2026’s Korean book charts showed adult fiction keeping unusual visibility inside general bestseller lists, led again by 프로젝트 헤일메리 (Project Hail Mary) and a cluster of Korean literary titles. Nonfiction remained firm, but its strongest showing came less from hard current-affairs books than from essays, practical humanities, and self-guidance titles such as 인생을 위한 최소한의 생각 (The Minimum Thinking for Life) and 사랑이 있으니 살아집디다 (I Live Because There Is Love).

Introduction

This report covers April 1–30, 2026, the most recent full calendar month.

The clearest April pattern was not a single universal No. 1 across all retailers. Instead, the month produced a repeat group. On Yes24’s monthly fiction chart, 프로젝트 헤일메리 (Project Hail Mary) led the category, followed by 안녕이라 그랬어 (I Said Goodbye). On Aladin’s monthly overall list, 프로젝트 헤일메리 (Project Hail Mary) also held a top-tier position, while 안녕이라 그랬어 (I Said Goodbye) and 해파리 만개 (Jellyfish in Full Bloom) both placed inside the top ten.

Nonfiction remained visible, but April’s demand leaned toward reflective and instructional reading. Yes24’s humanities monthly chart was led by 인생을 위한 최소한의 생각 (The Minimum Thinking for Life), with 이향인 (The Inward Person) and 완벽한 원시인 (The Perfect Primitive) immediately behind it, while Yes24’s essay monthly chart put 사랑이 있으니 살아집디다 (I Live Because There Is Love) at No. 1. Aladin’s overall monthly list likewise kept 무례한 세상에서 나를 지키는 법 (The Art of Distance) and 인생을 위한 최소한의 생각 (The Minimum Thinking for Life) in strong positions.

Fiction Bestsellers in Korea

Adult fiction had a better month than a simple glance at overall bestseller lists might suggest. Even with children’s publishing, test-prep, and event-driven books occupying many top slots on mixed retail charts, literary and translated fiction continued to recur across platforms, and several April releases entered visible positions quickly.

Yes24 Fiction Bestsellers

1. 프로젝트 헤일메리 (Project Hail Mary) — No. 1 on Yes24’s April monthly fiction chart.
2. 안녕이라 그랬어 (I Said Goodbye) — No. 2.
3. 소년이 온다 (Human Acts) — visible in the monthly fiction top tier at No. 3 on the chart sequence.
4. 절창 (Severance) — still visible at No. 4 in the eBook fiction monthly list and No. 22 on the print-focused fiction monthly page, showing continued carryover demand around Gu Byeong-mo’s work across Yes24 surfaces.
5. 급류 (Torrent) — visible at No. 17 on the monthly fiction page.
6. 바깥은 여름 (Outside Is Summer) — visible at No. 18.
7. 죽은 왕녀를 위한 파반느 (Pavane for a Dead Princess) — visible at No. 19.
8. 데미안 (Demian) — visible at No. 20.
9. 나의 친구들 (My Friends) — visible at No. 21.

What stood out on Yes24 was the coexistence of a translated commercial SF hit, current Korean literary fiction, and durable literary backlist. 프로젝트 헤일메리 (Project Hail Mary) remained the cleanest single fiction leader, but the broader list suggested that readers were still buying prize-adjacent, canon-adjacent, and backlist Korean fiction rather than treating April as a purely new-release month.

Aladin Fiction Bestsellers

1. 프로젝트 헤일메리 (Project Hail Mary) — No. 2 on Aladin’s monthly overall chart.
2. 안녕이라 그랬어 (I Said Goodbye) — No. 6.
3. 해파리 만개 (Jellyfish in Full Bloom) — No. 7.
4. 2026 제17회 젊은작가상 수상작품집 (2026 17th Young Writers’ Award Collection) — No. 11.
5. 괴테는 모든 것을 말했다 (Goethe Said Everything) — No. 13.
6. 오후의 마지막 잔디 (The Last Lawn of the Afternoon) — No. 19.
7. 모순 (Contradiction) — No. 20.

Aladin’s fiction signal was slightly broader than Yes24’s. It still favored 프로젝트 헤일메리 (Project Hail Mary), but it also gave strong space to Korean literary fiction and short-form literary publishing, especially 안녕이라 그랬어 (I Said Goodbye), 해파리 만개 (Jellyfish in Full Bloom), and the 젊은작가상 (Young Writers’ Award) collection.

Nonfiction Bestsellers in Korea

April’s nonfiction picture was steadier than fiction’s, but it was also more concentrated. The strongest books were not heavily news-reactive titles. Instead, the lists pointed toward essays, practical humanities, self-interpretation, and relationship-oriented reading.

Yes24 Nonfiction Bestsellers

1. 인생을 위한 최소한의 생각 (The Minimum Thinking for Life) — No. 1 on Yes24’s April humanities monthly chart.
2. 이향인 (The Inward Person) — No. 2 on the same humanities chart.
3. 완벽한 원시인 (The Perfect Primitive) — No. 3 on the humanities chart.
4. 여덟 단어 (Eight Words) — No. 4 on the humanities chart.
5. 사랑이 있으니 살아집디다 (I Live Because There Is Love) — No. 1 on Yes24’s April essay monthly chart.
6. 악수도 없이 헤어졌다 (We Parted Without Even a Handshake) — No. 2 on the essay chart.
7. 다정한 사람이 이긴다 (Kind People Win) — No. 3 on the essay chart.
8. 너를 아끼며 살아라 (Live While Cherishing Yourself) — No. 5 on the essay chart.

Yes24’s nonfiction structure was notably split. Humanities favored intellectually packaged self-guidance and readable general knowledge, while essays leaned toward testimony, consolation, and reflective prose. The strongest overlap between those zones came through books that promised usable orientation rather than topical argument.

Aladin Nonfiction Bestsellers

1. 무례한 세상에서 나를 지키는 법 (The Art of Distance) — No. 10 on Aladin’s monthly overall chart.
2. 인생을 위한 최소한의 생각 (The Minimum Thinking for Life) — No. 16.
3. 내면 근력 (Inner Strength) — No. 20.
4. 완벽한 원시인 (The Perfect Primitive) — No. 24.
5. 부의 사다리에 올라타라 (Climb the Ladder of Wealth) — No. 23, representing the month’s more directly financial-practical strand.

Monthly Trends in Korean Books

Translated fiction stayed unusually strong

The single clearest cross-platform fiction story was 프로젝트 헤일메리 (Project Hail Mary). It was No. 1 on Yes24’s April fiction monthly chart and No. 2 on Aladin’s April monthly overall list. That makes it the month’s most obvious fiction crossover title.

Korean literary fiction kept broad chart visibility

April was not only a translated-fiction month. 안녕이라 그랬어 (I Said Goodbye) ranked No. 2 on Yes24’s fiction monthly chart and No. 6 on Aladin’s overall monthly chart, while 해파리 만개 (Jellyfish in Full Bloom) and the 젊은작가상 (Young Writers’ Award) collection also surfaced strongly on Aladin.

Backlist literary demand remained active

Yes24 and Aladin both showed continuing life for older literary titles. Yes24’s fiction monthly page still carried 소년이 온다 (Human Acts), 바깥은 여름 (Outside Is Summer), 죽은 왕녀를 위한 파반느 (Pavane for a Dead Princess), and 데미안 (Demian), while Aladin kept 모순 (Contradiction) in the monthly top twenty.

Humanities outperformed hard topical nonfiction

On Yes24’s humanities monthly chart, 인생을 위한 최소한의 생각 (The Minimum Thinking for Life), 이향인 (The Inward Person), and 완벽한 원시인 (The Perfect Primitive) formed the leading cluster. Aladin’s overall monthly list echoed that preference with 인생을 위한 최소한의 생각 (The Minimum Thinking for Life) and 완벽한 원시인 (The Perfect Primitive) still visible.

Essay demand centered on witness and reassurance

Yes24’s essay monthly page was led by 사랑이 있으니 살아집디다 (I Live Because There Is Love), followed by reflective or consolatory essay titles such as 악수도 없이 헤어졌다 (We Parted Without Even a Handshake) and 다정한 사람이 이긴다 (Kind People Win). That points to demand for personal testimony and emotional steadiness rather than polemical essay writing.

New April releases did break through, but selectively

Several April 2026 titles entered visible positions quickly, including 해파리 만개 (Jellyfish in Full Bloom) on Aladin and 사랑이 있으니 살아집디다 (I Live Because There Is Love) on Yes24’s essay chart. But the month was not dominated by novelty alone; established backlist and February-March releases still controlled much of the adult reading conversation.

What Changed From Last Month

The cleanest month-over-month signals came from Yes24’s April pages, which display movement against the previous monthly position. On the overall monthly list, 프로젝트 헤일메리 (Project Hail Mary) rose one spot to No. 2, 인생을 위한 최소한의 생각 (The Minimum Thinking for Life) climbed 12 places to No. 14, 완벽한 원시인 (The Perfect Primitive) rose 10 places to No. 18, and 무례한 세상에서 나를 지키는 법 (The Art of Distance) rose 15 places to No. 19.

On Yes24’s fiction monthly page, 프로젝트 헤일메리 (Project Hail Mary) held the top position, while 안녕이라 그랬어 (I Said Goodbye) was at No. 2 for April. In practical terms, that means translated SF kept its leadership while Korean literary fiction remained directly behind it rather than falling away.
