Overview

Doona used to be the most popular member of a K-pop idol group, until she wasn't, walking away from her career and disappearing into an ordinary Seoul share house. Won-jun, starting his first day of college, has no idea any of that history exists when he moves into the room upstairs and just sees an oddly familiar, prickly woman who doesn't want to be bothered. Song-A Min's webtoon spends its 153 chapters on what happens when those two people, one trying to reinvent herself and one just trying to get through college, end up living on top of each other.

You may already know this story without having read it. Netflix adapted it in 2023 as Doona!, starring Bae Suzy, and the drama made enough of a splash that it's easy to forget the source material is a completed webtoon original with its own version of events, one that doesn't match the show beat for beat.

What it does well

Doona is written as a genuinely damaged person rather than a quirky love interest with a sad backstory attached for flavor. Her prickliness, her drinking, and her inability to trust people who suddenly want to be close to her all track directly back to what fame did to her, and the book takes its time letting Won-jun, and the reader, earn access to who she actually is underneath that surface. The slow-burn pacing is a real strength here: arguments and misunderstandings get room to actually matter instead of resolving by the next chapter, which is rarer than it should be in the genre.

The supporting cast helps too. Won-jun's roommates, one disciplined and love-averse, one an unlucky hopeless romantic, and his childhood friend with her own unspoken feelings for him, give the book a lived-in, group-house texture instead of making every scene orbit the central couple. It reads less like a two-hander and more like an actual slice of a messy shared life, which makes the romance itself feel earned rather than engineered.

Where it falls short

Doona's celebrity-trauma arc leans hard on repetition. The same insecurities and self-sabotaging patterns resurface across many chapters, and if you're not invested in watching her work through them slowly, some stretches read as treading water rather than building toward anything new. The Netflix adaptation's higher profile also means plenty of readers will come in already knowing where the drama version ends up, which can color expectations even though the webtoon's own ending takes a genuinely different path.

Verdict

Grounded, slow-burn romance that earns its Netflix adaptation rather than just riding the platform's algorithm, anchored by a female lead who gets real interiority instead of just charm. Worth reading on its own terms even if you've already seen Doona!, since the webtoon isn't just a lower-budget rerun of the same story, it gets there differently.
