ㅑEnglish) Having majored in oriental art and art theory, author Yeojune Yoon creates stories, and plans for exhibitions. He likes things that seem complicated, twisted, and tangled with blurred boundaries. He may be timid, but he does save energy to be more vocal when necessary. He co-wrote the essay At the Time, My Grandmother and wrote and illustrated Today, I Must Ask Dad How He's Doing, his first-ever picture book.

(Japanese) 物語を作り、展示を企画します。東洋画と美術理論を勉強しました。容易くないもの、もつれあってるもの、複雑に絡み合っているものが好きです。一緒に書いたエッセイに『その時、おばあちゃん』があります。『今日はお父さんの安否を聞かなければなりません』は初めて絵と文を書いた絵本です。
