Kohaku figured it out. Not sure how, but she did it.
Sensei is such a giga chadette, came in, fixed the problem, and then leaves, or at least tried to.
It found it funny that Akane was a little jealous of Kohaku for bagging such a fine woman.
So did she know or not ?
it look like she did, then didn't, then did, then didn't.
but next is last chapter, i suppose the been is finally out for real this time
Kinda weird how we've gotten every indication that she wasn't aware of her identity for the entire work, just for it to flip-flop now with seemingly nothing to have caused the realization..? I guess we'll find out next chapter. Sad that it has to end so soon, it feels like the story barely has gotten started tbh
