Assuming the title translates to something close to "I wonder when he'll tell me his name," which is subsequently the last line in this Oneshot, I felt like this piece tied itself together really well (google says "a flower without a name," but japanese is context based so idk). It gets a 8.5/10, It's short, it covers so much time, it's sweet, and it doesn't leave you in pain, it leaves you with the thought that the story will continue on whether you're there to see it or not. 1.5 points docked for a bit of discomfort around what age group the two were in when they met. And for a bit of unexplained out of character behavior, but that's all up to preference.
AAAA THIS AUTHOR IS THE BEST this story depict how erwin and Levi first met and how levi always remember erwin despite thinking erwin never remember him
