原始人彼氏 [Primitive Boyfriend]

In this short, playful 2017–2018 manga series from Hakusensha, a modern young woman finds herself in an unlikely romance with a handsome but utterly prehistoric caveman. The comedy and charm come from their absurd cultural clash: he brings her freshly hunted mammoth, she introduces him to cell phones and convenience stores. Written and drawn by a single creator, Primitive Boyfriend is a lighthearted, three-issue gag about love that transcends—or rather, ignores—tens of thousands of years of evolution.
