I kept staring at the answer for a difference between this and I couldn’t see anything. Am I just missing something really obvious?
For reference, when I was typing this, I got halfway through it (typing the “yuu” half), tabbed out, then tabbed back in and accidentally wrote “BE” in all caps because I had caps lock on. I’m not sure if any of that would confuse wanikani but that’s the only unusual thing I did when typing the answer in.
