On the other hand, 埋まる (うまる (umaru)) maps to "to be buried; to be filled; to be clogged; to be packed" (Syllabus Level: N3) and represents Refers to objects being buried underground, holes or gaps being filled up, or schedules/seats being fully packed or booked. Intransitive verb. Opposing word: 埋める. Often used as 予定が埋まる or 席が埋まる. ⚠️ Haruka's Voice Column: 'To be filled! "My weekend schedule is completely filled with dates with you, Haruka-san!" ...っ! S-Schedule filled with dates! B-Baka! Don't show off your schedule! But... since it's filled, make sure you treat me to the best cafe and don't look at anyone else! dummy!' / 【ハルカ部長のワンポイント指導】『うまる（埋まる）よ！『ハルカ部長、僕の今月の週末スケジュールは、あなたとのデート予定だけで完全に埋まりました！幸せです！』って…っ！スケジュールが埋まる！バカ！/// 当たり前でしょ！私のカレンダーだって、あんたとのデートと愛の計画だけで永久に「満席（ソールドアウト）」なんだから！』.
