No time to leisurely eat with 呑気

美少女戦士セーラームーン » Volume 8 » Page 58

After an enemy attack changes Usagi and Mamoru into kids, Usagi wakes to find the two of them living together as a couple.

As Usagi wanders into the dining room, Mamoru is placing a plate of french toast on the table. He greets her and asks Usagi what type of jam she wants on her toast.

Usagi responds, then realizes she needs to get to school.

うさぎ:
「あたし ライムのマーマレードッ」
"I'll have lime marmalade!"
「ってそんな呑気(のんき)()べてるヒマなんかあたしにはっっ」
"Ah, I don't have any time to be leisurely eating!"

The に after 呑気(のんき) makes it an adverb.
