If you loved Nisekoi: False Love, try Kaguya-sama Final: Love Is War
A bridge between a film you've already seen and one most people haven't. Kaguya-sama Final: Love Is War has roughly 3.6× fewer votes than Nisekoi: False Love — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Hayato Kawai, and they both carry the cozy, foreign gem, playful mood tags, and they sit in Comedy / Romance territory. If that's the register that drew you to Nisekoi: False Love, the second film will land in a comparable space — through a different lens.
What Kaguya-sama Final: Love Is War is
A live-action manga adaptation about high-schoolers playing mind games? Sure, we've seen that. Two class presidents refuse to admit they like each other, so they try to make the other confess. In the end, it's just a fairly standard will-they-won't-they, but with extra steps.
