Manhwa Like Our Secret Alliance: 4 Fake-Dating Picks

TL;DR: Manhwa like Our Secret Alliance, 4 completed picks: 'Til Debt Do Us Part (closest match, practical-arrangement-to-real-feelings), Super Secret and Days of Hana (childhood-friend slow burns with a werewolf twist), and A Business Proposal (the genre's most iconic fake-dating premise, adult office setting). All four verified completed with real endings.

Key Takeaways

• Our Secret Alliance's specific hook is two tropes at once: childhood friends who drifted apart, and a fake arrangement that starts practical and turns real. Not every pick on this list does both.
• 'Til Debt Do Us Part is the closest emotional match: an old friend proposes a practical arrangement that solves a real problem and becomes genuine.
• Super Secret and Days of Hana share the childhood-friends-to-lovers slow burn but add a werewolf-companion fantasy element Our Secret Alliance doesn't have.
• A Business Proposal is the genre's most recognizable fake-dating manhwa, recommended for the trope itself even though the setting shifts to adult office romance.
• All four are completed, 72 to 141 chapters, so none carry the risk of an unresolved ongoing arc.

Manhwa like Our Secret Alliance: what actually made the cut

Our Secret Alliance works because it stacks two tropes readers don't usually get together: the childhood-friends-who-drifted-apart setup, and a fake arrangement (an "alliance" to get parents off their backs) that stops being fake partway through. A lot of "manhwa like Our Secret Alliance" lists just grab anything tagged fake-dating and call it a day, which misses half of what actually made the original work.

The four picks below split cleanly by which half of that formula they lean into. None hits both tropes as precisely as the original does, so each entry below states plainly which part of the appeal it's actually recommended for.

For where to actually read any of these picks, our guide covers platform basics for readers newer to the format.

1. 'Til Debt Do Us Part

'Til Debt Do Us Part by Flowbee

This is the closest match on the list, and it isn't close. Subin keeps turning down the matchmaker dates her mom sets up, until an old school friend proposes something more direct: marry him, and her debt problem disappears. That's a practical, transactional starting point, the same shape as Our Secret Alliance's fake-alliance premise, and it develops into real feelings the same way. Completed at 72 chapters, free on official WEBTOON, updated weekly during its run.

2. Super Secret

Super Secret by Eon

Super Secret keeps the childhood-friend half of Our Secret Alliance's formula and adds a fantasy twist the original doesn't have: the boy-next-door childhood friend is secretly a werewolf. It's a lighter, more slice-of-life read than Our Secret Alliance, with a chibi-leaning art style that softens even the more dramatic beats. Completed at 141 chapters on WEBTOON, originally serialized on Naver Webtoon from 2015 to 2018.

3. Days of Hana

Days of Hana

Same core trope as Super Secret, childhood friend who's secretly a werewolf, but Days of Hana plays it straighter and heavier. Haru and Hana's relationship has been complicated since childhood, and the story leans into the tension and emotional weight rather than the comedy. If Our Secret Alliance's slow-burn stretch (the part before chapter 40 that tests patience) was your favorite part rather than a hurdle, Days of Hana's pacing will feel familiar. Completed at 113 chapters, free on WEBTOON, updating Wednesdays during its run.

4. A Business Proposal

A Business Proposal by NARAK (art), Haehwa (original story)

This is the one to read for the fake-dating mechanic specifically, not the childhood-friends setup, since it drops that half of the formula entirely. Ha-ri stands in for her friend on a blind date arranged by her friend's grandfather, and the date turns out to be with her own company's CEO. The fake-arrangement premise escalates from there into one of the genre's best-known office romances. It's an adult workplace setting rather than Our Secret Alliance's high-school one, so the tone shifts, but the "starts as a scheme, becomes real" engine is the same one driving both stories. Completed at 124 chapters.

A Business Proposal is also the pick with the widest general name recognition of the four, partly because the K-drama adaptation pulled in viewers who never touched the source manhwa. That crossover audience is worth knowing about if you're the kind of reader who prefers going in without a screen adaptation already shaping your expectations: the drama follows the webtoon closely enough that watching it first will spoil most of the manhwa's structure.

Manhwa like Our Secret Alliance: which one to pick first

If the childhood-friends-drift-apart-then-reconnect arc was what hooked you, start with 'Til Debt Do Us Part for the closest match without a fantasy element, or Days of Hana if you don't mind a werewolf twist and want a heavier emotional read. If it was specifically the fake-arrangement-becomes-real mechanic, A Business Proposal is the genre's most polished version of that exact structure, just in an adult setting instead of a high-school one.

None of the four are ongoing series, which matters if Our Secret Alliance's clean, fully-resolved ending was part of what you liked about it in the first place. All four commit to an actual endpoint rather than leaving the central relationship in an indefinitely-serialized holding pattern.

If a completed, no-cliffhanger ending is the priority over any specific trope match, covers a much wider set of finished series across every genre.
