Why would anyone assume that you know them better than themselves? Maybe you're right that the uke doesn't know but you don't tell them that. Imagine you're seeing a clearly gay person, would you tell that person they're gay?
I mean they did have like a whole classroom lecture and I assume it wasn't just discussed once considering they're not in college.
Why didn't the Seme told the uke that's the uke is an Omega? Why?? The uke clearly didn't know.
