First time home owner, first time having my own bed. What to buy?

Hello! After YEARS of sharing a room and being on a crappy bed, im finally a first time home owner at magkakaroon na ako ng sarili kong kwarto wahaha! nalilito lang ako pagdating sa need kong bilhin for my bed. Nakabili na ako ng frame at mattress. alam ko need ko bumili ng bed sheets, unan at pillow cases. Pero ano pa ba yung comforter, duvet, at blanket? kailangan ko ba yang tatlo? 🤣🤣 at san ba makakabili yung di naman super mahal pero can last me a while? im just looking for maximum comfort, maenjoy ko lang tong small milestone ko 🥹🥹 ty ty!
