ルーヴル美術館でぬい活してたらスタッフのお姉さんがモナ・リザの近づいてはいけないエリアに広ぬいを置いてくれて周囲がざわつきました、メルシーありがとう😭😭😭

While doing plushie activities at the Louvre Museum, a staff lady placed a giant plush right in the no-approach area near the Mona Lisa, and it caused a stir all around—merci, thank you 😭😭😭

Hironui being "translated" as giant plush is extremely funny to me
