Inazawa Megumi (Lee Seyeon)

Inazawa Megumi—Korean name, Lee Seyeon. Born to a Japanese father and Korean mother, she grew up under a household rule of Japanese on weekdays, Korean on weekends, which gave her a dual feel for language. To Korean relatives she’s “Seyeon,” to the publishing world she’s “Megumi,” and she uses both. Megumi is based in Tokyo and shuttles to Seoul as needed. By day she roams alleys and station platforms; by night she opens a whiteboard app to draft a suspicion matrix (suspect × motive × opportunity) and cycles hypothesis → falsification. She builds puzzle and mechanism first in her drafts, then breathes life into the characters on the second pass. Her main lanes are thriller romance, twist-driven narratives, and reality-grounded detective drama—earning trust with everyday detail and landing a perspective flip in act three. A reality-mystery novel she published in her third year recently surged back onto bestseller lists, and between signings and OTT adaptation meetings she hosts public debate sessions with readers.
