Romantic Killer

Both shows fall into the subgenre of meta-romcoms that use a layer of meta-irony to get you in the door with a whacky concept, and slowly peel back the layers to reveal a more standard romcom at its core.
I would say Romantic Killer is more creative in its animation and directing, but both do a good job at treating situations and circumstances as building blocks that are obvious to both the MC and the audience.
