How I Cracked Doona’s Ending Mystery Step by Step
Man, I gotta tell ya, that Doonna ending left me scratching my head like crazy. Woke up this morning still thinking about it, coffee tasting like confusion. Said screw it, grabbed my notebook and fired up Netflix again. This ain’t over.

First thing I did? Rewatched the final 15 minutes. Slowed that playback right down. Needed to catch every little flicker on Doona’s face, every weird object in Won-jun’s apartment. Seriously squinted at my screen like a detective at a crime scene. Noticed stuff I totally missed before:
- That damn music box wasn’t just background noise. Its melody was the same damn tune Doonna hummed way back in episode 3. Recognized it instantly this time.
- Won-jun flipping through his sketchbook. Zoomed in real close. His drawings weren’t just random scenes. Hidden in the smudges and shadows, I swear I saw faint outlines of places before the accident.
- Doona staring out the window. Wasn’t just brooding. Her eyes kept focusing on something specific across the street – an old, closed-down record store we saw one quick flash of ages ago.
Okay, clues collected. Felt like piecing together Ikea furniture without the instructions. Flipped open my dusty notebook from the first watch. See, I scribble crazy notes while binging. Found my page about episode 5. I’d written “Granny talks abt destiny? Actual fortune teller ref?” in my messy handwriting near a big splotch of soup. Went digging.
Grabbed my tablet, pulled up episode 5 on that tiny split screen while the finale played on the TV. Cramped my neck like hell. Rewound to Won-jun visiting his gran. She’s muttering that cryptic line about “souls finding the music box path back.” Back then, sounded like sweet old lady rambling. Side-by-side with the finale? Chills. Slammed my notebook down. “Path back” meant memory. The music box was her damn anchor to the life before the crash.
The record store thing bugged me. Paused the finale again. Why keep showing that spot? Searched my notes like a maniac. Episode… maybe 7? Ah! When Won-jun walks Doona home drunk. Background noise! Heard some kinda jazz song faintly playing. Ripped off my headphones, blasted the audio on my decent speakers. Dug into the show’s OST playlist later. Bingo. Found “Midnight Stroll (Instrumental).” Matched the episode 7 snippet. That tune was supposedly played constantly at that closed record store. Her parents owned it. She heard her past walking by that spot everyday.
Suddenly, Won-jun’s sketchbook sketches clicked. That bridge drawing with the weird smudge? Wasn’t a mistake. Covered up the truck from the accident scene he subconsciously remembered. Dude was drawing her past trauma without realizing it. The music box melody unlocked it for Doona. The record store visual triggered the sound memory. Boom.

That final scene ain’t just them getting back together. It’s two people finally seeing the whole damn puzzle after being stuck with scattered pieces forever. He remembers how her pain started. She remembers who she truly was before the world made her “Doona.” They got the missing parts. Mystery friggin’ solved. All it took was replaying scenes, squinting at pixels, blasting audio tracks, and connecting my own messy soup-stained notes. Feels good, man. Feels real damn good.
