下の階には澪がいる

"The Girl Downstairs," known as "Lee Doo-na!" in South Korea, is a webtoon created by Korean artist Min Songa. It was serialized on Naver Webtoon from July 2019 to July 2022. The story revolves around college student Sugiura Yo who moves into a new apartment and discovers that his downstairs neighbor is a mysterious ex-idol named Kisaragi Mio. Yo initially tries to avoid her but becomes increasingly intrigued by Mio's enigmatic life. The series, which blends elements of youth, romance, and comedy, has gained significant popularity and has been adapted into a Chinese animated series and a Korean live-action drama. The anime adaptation premiered in July 2024 on Fuji TV's "B8station" block in Japan, featuring Maaya Sakamoto as the voice of Mio and Keisuke Kawamoto as Yo. The live-action drama, titled "Doona!", is available on Netflix. The success of the webtoon has also led to the creation of spin-off works, such as performances in the South Korean reality music show "Webtoon Singer," where K-pop artists combine webtoons with extended reality technology.
