Reincarnated for 30 Years—Turns Out It Was a Romance Fantasy?!

After living three decades in a new world, the protagonist discovers they've been unwittingly living inside a romance fantasy novel, not the typical action-adventure fantasy they assumed. Thirty years of misinterpreted tropes and genre-blind decisions come crashing down as the romantic plotlines they overlooked finally catch up to them. Can they survive the impending love triangle (or hexagon) when they've been preparing for dungeon raids and dragon slaying instead?
