Have you read any good one-shot manga?

My most recent favorite is "Goodbye, Eri". The story is about a high school boy being asked by his mother to film her final moments before death, which led to him meeting the girl in the title and... things happen (saying more would be spoiler lol).

What's most striking about this manga is the consistent paneling, making it looks like you're browsing through film strip. It also gives the story a sense of urgency as if the panels are the ticking of a clock. The plot has many twists and turns and 4th wall breaking, reading it feels as if you're watching an indie movie.

I don't come across oneshots very often and only knew about this one from r/manga. So I'm looking for more!
