How to say "Be" in Japanese

When translating "be" into Japanese, you must choose carefully between 退院する and 満足する. In Japanese, 退院する (たいいんする (taiin suru)) is typically associated with "to be discharged from hospital; to leave hospital" (Syllabus Level: N3) and represents Refers to a recovered patient leaving the hospital, being officially discharged. Intransitive verb. Opposing word: 入院する. Often used as 病院を退院する. ⚠️ Haruka's Voice Column: 'To leave hospital/be discharged! "Thanks to your warm care, I recovered completely and left the hospital, Haruka-san!" ...っ! Discharged! B-Baka! I'm glad you are healthy. But don't think leaving the hospital gets you out of my doting hugs! I will continue to pamper you right by my side forever! dummy!' / 【ハルカ部長のワンポイント指導】『たいいんする（退院する）よ！『ハルカ部長、あなたの温かい看病のおかげで、すっかり元気になって退院する（退院できました）！』って…っ！退院！バカ！/// 元気になってよかったわね。でも、退院したからって私の看病（甘デレハグ）から離れられると思わないで！一生隣で甘やかし続けるわ！』. On the other hand, 満足する (まんぞくする (manzoku suru)) maps to "to be satisfied; to be contented; to be pleased with" (Syllabus Level: N3) and represents Refers to being deeply satisfied with system performance, contented with business outcomes, or pleased with a lover's doting care. Opposing word: 不満に思う. Often used as 結果に満足する or 満足度が高い. ⚠️ Haruka's Voice Column: 'To be satisfied/contented! "Snuggling close to you alone like this makes me the most satisfied in the universe, Haruka-san!" ...っ! Greatly satisfied! B-Baka! Of course you are! Neither failing nor complaints allowed! Savor the sweetest, most luxurious satisfaction right next to my warmth daily for the rest of your life! dummy!' / 【ハルカ部長のワンポイント指導】『まんぞくする（満足する）よ！『ハルカ部長、あなたと二人きりで寄り添うこの時間、僕は宇宙一満足する（大満足です）！』って…っ！大満足！バカ！/// 当然よ！落第も不満もなし！一生私の温もりの隣で、世界一贅沢で甘々な満足を毎日噛み締め続けなさいよね！』. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
