While there are parts that are tragedy (Shiki's mom, the village of snake people getting burnt, and Akisa's brother's bullshit) and drama (Kon and Kabane's relationship, Aya and Kon's rivalry, Inari being a bitch), I think that romance is still much more of present than those two. imo, adding those two tags would be like adding the crossdressing tag to a series because in one chapter a girl pretended to be a guy. Not that I don't think that those are parts, I just don't think that they're as important parts
