The romance genre is perhaps one of the most popular and loved anime genres of all time. It’s an evergreen landscape of authentic, tropey, cringey, and heartwarming stories that have kept the audience engaged for decades. Whether it’s first love, a messy high school love triangle, or a struggling marriage, the romance genre in anime has dominantly told stories that are both formulaic and standalone. One of the key qualities of the romance genre is its ability to complement almost every other sub-genre. Romance is so volatile that it never feels out of place when inserted in a hardcore shonen, a comedic isekai, or even a spy thriller. Viewers can enjoy an adrenaline-infused shootout in a high-octane anime, but that same story can accommodate a fleeting love affair between the cold and calculated heroine and the handsome underdog.
