Loved the dialogue in this & it contained Erwin's hilarious "I have to marry him. Soon." But the design for Levi was the least like his appearance I've seen, which made it a little hard to get into. If this were a longer work it wouldn't matter as much, but it stuck out being a oneshot.
rereading this in January 20 22, I had no issue with the character design and really enjoyed the story.
